137140-69-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137140-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,4 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137140-69:
(8*1)+(7*3)+(6*7)+(5*1)+(4*4)+(3*0)+(2*6)+(1*9)=113
113 % 10 = 3
So 137140-69-3 is a valid CAS Registry Number.

A chemoenzymatic synthesis of optically-active dihydropyridines

Holdgruen, Xenia K.,Sih, Charles J.

, p. 3465 - 3468 (1991)

A biocatalytic asymmetric synthesis of optically-active dihydropyridines has been developed. The method entails the enantiotopically-selective solvolysis of the sterically unhindered ester 13 in n-BuOH/H2O catalyzed by Pseudomonas lipases.
