133608-96-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133608-96-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,0 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133608-96:
(8*1)+(7*3)+(6*3)+(5*6)+(4*0)+(3*8)+(2*9)+(1*6)=125
125 % 10 = 5
So 133608-96-5 is a valid CAS Registry Number.

An efficient synthesis of optically active 2-alkylsuccinate monoesters
Larcheveque,Petit
, p. 162 - 164 (2007/10/02)
Optically active 2-alkylsuccinates were obtained as their monoesters by stereospecific substitution of the p-toluenesulfonates or p-nitrobenzenesulfonates of α-hydroxy esters with sodium di-tert-butyl malonate, followed by hydrolysis and decarboxylation of the resulting diacids.
