Check Digit Verification of cas no

The CAS Registry Mumber 41097-47-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,0,9 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 41097-47:
(7*4)+(6*1)+(5*0)+(4*9)+(3*7)+(2*4)+(1*7)=106
106 % 10 = 6
So 41097-47-6 is a valid CAS Registry Number.

Ruthenium(ii)-catalysed 1,2-selective hydroboration of aldazines

Gunanathan, Chidambaram,Pradhan, Subham,Thiyagarajan, Subramanian

supporting information, p. 7147 - 7151 (2021/08/30)

Herein, an efficient and simple catalytic method for the selective and partial reduction of aldazines using ruthenium catalyst [Ru(p-cymene)Cl2]2 (1) has been accomplished. Under mild conditions, aldazines undergo the addition of pinacolborane in the presence of a ruthenium catalyst, which delivered N-boryl-N-benzyl hydrazone products. Notably, the reaction is highly selective, and results in exclusive mono-hydroboration and desymmetrization of symmetrical aldazines. Mechanistic studies indicate the involvement of in situ formed intermediate [{(η6-p-cymene)RuCl}2(μ-H-μ-Cl)] (1a) in this selective hydroboration.

Synthesis and Antimicrobial Activity of Some New Coumarin and Dicoumarol Derivatives

El-Metwally, S. A.,Regal, M. K. A.,Shaban, S. S.

, p. 438 - 447 (2020/06/30)

Abstract: Phase transfer catalysis reaction of 4-hydroxy-6-methyl-2H-chromen-2-one with alkyl halides afforded C4 oxygen alkylation products of 2H-chromen-2-one derivatives in appreciative yield, whereas with phenyl isothiocyanate gives the C3 addition product of 4-hydroxy-6-methyl-2-oxo-N-phenyl-2H-chromene-3-carbothioamide, also one pot three component phase transfer reaction was investigated. Treatment of 4-hydroxy-6-methyl-2H-chromen-2-one with aromatic aldehydes in different molar ratios gives 3?arylidine and the dicoumarol derivatives. However pyrano chromene and pyrano pyridine were obtained by reaction of arylidine with ethyl acetoacetate through Michael cycloaddition reaction. The stability of pyrone ring in 3-arylidine and dicoumarol towards different nucleophilic reagents under reflux and/or fusion conditions has been studied by the action of, hydrazine hydrate, ammonium acetate, methyl amine and p-toluidine afforded compounds 1,2-bis(benzo[d][1,3]dioxol-5-ylmethylene)hydrazine, 1,2-bis(4-methoxybenzylidene)hydrazine and 2,6-bis((2,6-dihydroxy-3-methylphenyl)(hydroxy)methylene)-1-(4-methoxyphenyl)-4-(p-tolyl) piperidine-3,5-dione derivatives. The antimicrobial activity of some synthesized compounds has been investigated.

Glucose:urea:NH4Cl low melting mixture for the synthesis of symmetric azines

Theresa, Letcy V.,Shaibuna,Sreekumar

, p. 3148 - 3160 (2019/09/03)

Alternate reaction media have become very important due to the problems created by the highly volatile nature of the solvents. The deep eutectic mixture is a kind of an alternate reaction medium which has emerged in recent years. Low melting mixtures were introduced by making the deep eutectic mixture more cost-effective and renewable by introducing carbohydrates into it. The properties of low melting mixtures include easiness to prepare, usage of low-cost components, biodegradability, solubility in water, easy separation from organic compounds, etc. The low melting mixtures such as glucose:urea:NH4Cl, glucose:ChCl, glucose:urea:ChCl, glycerol:urea:NH4Cl, and ethylene glycol:urea:NH4Cl were used in different ratios for the reactions. The properties such as viscosity, density, acidity, glass transition temperature, and thermal stability were studied. An unusual method for the synthesis of symmetrical azines is introduced wherein benzaldehyde and hydroxylamine are reacted in the presence of glucose:urea:NH4Cl. The method of synthesis needs only less reaction time, temperature and the product was easily separated. The products were confirmed using GC-MS and NMR techniques. The recyclability of glucose:urea:NH4Cl was studied.
