Check Digit Verification of cas no

The CAS Registry Mumber 153668-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,6,6 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 153668-12:
(8*1)+(7*5)+(6*3)+(5*6)+(4*6)+(3*8)+(2*1)+(1*2)=143
143 % 10 = 3
So 153668-12-3 is a valid CAS Registry Number.

The influence of α-amido/thioamido functionality in ester reduction with sodium borohydride

Roy, Atanu,Bar, Narayan C.,Achari, Basudeb,Mandal, Sukhendu B.

, p. 644 - 650 (2007/10/03)

Sodium borohydride in methanol smoothly reduces the esters of α-amino acids having N-acyl (orthioacyl)-N-alkyl (-NRCOR′ or -NRCSR′) substituents, producing amino alcohol derivatives. Esters with α-NHCOR or-CONRR′ functionality however remain unaffected. Electron-withdrawing property of the substituent appears to play a crucial role, anion formation with -NHCOR group perhaps diminishing its effect.
