Check Digit Verification of cas no

The CAS Registry Mumber 133392-35-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,9 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133392-35:
(8*1)+(7*3)+(6*3)+(5*3)+(4*9)+(3*2)+(2*3)+(1*5)=115
115 % 10 = 5
So 133392-35-5 is a valid CAS Registry Number.

Kinetic resolution of racemic alcohols with chiral carboxylic acids and dicyclohexylcarbodiimide

Chinchilla,Najera,Yus,Heumann

, p. 851 - 854 (2007/10/02)

The DCC-esterification method has been used to kinetically resolve racemic mixtures of alcohols. With simple chiral carboxylic acids, such as O-aryl lactic acids, in the presence of various basic catalysts, mixtures of the enantiomerically enriched alcohols (e.e. 50%) and the corresponding esters (d.e. 70%) have been obtained.
