92742-11-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92742-11-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,7,4 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 92742-11:
(7*9)+(6*2)+(5*7)+(4*4)+(3*2)+(2*1)+(1*1)=135
135 % 10 = 5
So 92742-11-5 is a valid CAS Registry Number.

Asymmetric synthesis of esters and acids
-
, (2008/06/13)
Stereoisomerically-enriched esters are prepared by treating a non-symmetrical ketene with a racemic or chiral tertiary-base-substituted alkylcarbinol. Optional hydrolysis of the esters gives the corresponding optically-active carboxylic acids correspondin
