107538-61-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 107538-61-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,5,3 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 107538-61:
(8*1)+(7*0)+(6*7)+(5*5)+(4*3)+(3*8)+(2*6)+(1*1)=124
124 % 10 = 4
So 107538-61-4 is a valid CAS Registry Number.

An efficient protocol for the oxidative hydrolysis of ketone SAMP hydrazones employing SeO2 and H2O2 under buffered (pH 7) conditions

Smith III, Amos B.,Liu, Zhuqing,Simov, Vladimir

experimental part, p. 3131 - 3134 (2010/03/24)

An effective oxidative protocol for the liberation of ketones from SAMP hydrazones employing peroxyselenous acid under aqueous buffered conditions (pH 7) has been developed. The procedure proceeds without epimerization of adjacent stereocenters or dehydration, in representative SAMP alkylation and aldol reaction adducts, respectively.

Diastereo- and enantioselective synthesis of syn-2,3-disubstituted 1,4-diketones via oxidative coupling of metalated hydrazones

Enders, Dieter,Müller, Peter,Klein, Daniela

, p. 43 - 44 (2007/10/03)

An efficient diastereo- and enantioselective synthesis of syn-2,3-disubstituted 1,4-diketones 4 is described. Key step of the procedure is the oxidative coupling of the metalated SAMP/RAMP-hydrazones 2 with iodine, followed by oxidative cleavage of the dimerized bishydrazones 3 with ozone and subsequent separation of the minor meso-isomer by chromatography. The d,l-isomers of the title 1,4-diketones 4 are obtained in good overall yields (20-64%) and high diastereo- and enantiomeric excesses (de ≥ 98%, ee = 80 - ≥95%).

Enantioselective Synthesis of (S)-(+)-2-Tridecanol Acetate, an Aggregation Pheromone Component of Drosophila mulleri

Enders, Dieter,Plant, Andrew

, p. 1241 - 1243 (2007/10/02)

The enantioselective synthesis of (S)-(+)-2-tridecanol acetate (ee = 93.5percent), an aggregation pheromone of Drosophila mulleri, is described.Key steps are the α-alkylation of the propiophenone SAMP-hydrazone (S)-2 (de 96percent) and the Baeyer-Villiger reaction of the ketone (S)-4.Key Words: (S)-(+)-2-Tridecanol acetate / SAMP-hydrazone / Baeyer-Villiger reaction / Pheromone, aggregation / Drosophila mulleri
