Check Digit Verification of cas no

The CAS Registry Mumber 129265-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,6 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129265-90:
(8*1)+(7*2)+(6*9)+(5*2)+(4*6)+(3*5)+(2*9)+(1*0)=143
143 % 10 = 3
So 129265-90-3 is a valid CAS Registry Number.

Enzyme-Catalyzed Reactions, 7. - Enantioselective Esterification of Racemic Cyanohydrins and Enantioselective Hydrolysis or Transesterification of Cyanohydrin Esters by Lipases

Effenberger, Franz,Gutterer, Beate,Ziegler, Thomas,Eckhardt, Elisabeth,Aichholz, Reiner

, p. 47 - 54 (2007/10/02)

Pure cyanohydrin enantiomers (S)-1/(R)-1 and their O-acyl derivatives (R)-3/(S)-3 are obtained from three different lipase-catalyzed reactions: (i) enantioselective hydrolysis of aliphatic and aromatic racemic cyanohydrin esters 3, ii) enantioselective ac
