27383-59-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 27383-59-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,3,8 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27383-59:
(7*2)+(6*7)+(5*3)+(4*8)+(3*3)+(2*5)+(1*9)=131
131 % 10 = 1
So 27383-59-1 is a valid CAS Registry Number.

Triphenylphosphine-mediated synthesis of the E/Z isomers of methyl 6-(1,2-di(methoxycarbonyl))-8-(ethyl carbamoylformyl)-2-oxo-2H-chromene-4- carboxylate

Yavari, Issa,Feiz-Javadian, Fakhrossadat

, p. 1011 - 1016 (2006)

Triphenylphosphine-mediated reaction of dimethyl acetylenedicarboxylate with ethyl (2-hydroxyphenylcarbamoyl)formate in boiling toluene produces a mixture of methyl 8-(ethyl carbamylformyl)-2-oxo-2H-chromene-4-carboxylate and the E/Z isomers of methyl 6-(

A Bis-Polydentate Oxamate-Based Achiral Ligand That Can Stabilize a Macrocyclic Mixed Valence Compound or Induce a 1D Helical Chain

Li, Ang,Li, Yanling,Chamoreau, Lise-Marie,Desmarets, Christophe,Lisnard, Laurent,Journaux, Yves

, p. 3311 - 3319 (2020)

The reaction of the N-(2-hydroxyphenyl)oxamate ligand (ohpma) has been investigated with cobalt(II) and copper(II) ions. It has led to two coordination compounds, (TMA)3[{CoIII(ohpma)2CoII(MeOH)2}sub

A new method for the preparation of unsymmetrical 1,4-substituted piperazine derivatives

Ortiz, Aurelio,Farfan, Norberto,Hoepfl, Herbert,Santillan, Rosa,Ochoa, Maria E.,Gutierrez, Atilano

, p. 799 - 811 (2007/10/03)

Symmetrical and unsymmetrical N,N'-piperazine derivatives of (-)- norephedrine and o-aminophenol were synthesized stereoselectively in yields >70% by reduction of the corresponding N,N'-ethylenebisoxazolidine heterocycles. The stereochemistry at the ring fusion carbons was established by NMR spectroscopy and X-ray crystallography.
