Check Digit Verification of cas no

The CAS Registry Mumber 212776-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,7,7 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 212776-45:
(8*2)+(7*1)+(6*2)+(5*7)+(4*7)+(3*6)+(2*4)+(1*5)=129
129 % 10 = 9
So 212776-45-9 is a valid CAS Registry Number.

, p. 5571 - 5574 (2007/10/03)

Porcine liver esterase (PLE)- or rabbit liver esterase (RLE)-catalyzed hydrolysis of the pro-S ester group of diethyl α-alkyl-α- (benzyloxycarbonylamino)malonates 2a-c afforded (R)-ethyl α-alkyl-α- (benzyloxycarbonylamino)malonates 3a-c each in excellent enantiomeric excess. Enantiodivergent reductions of these acid esters 3a-c readily furnished both the corresponding enantiomeric α-substituted serines (R)- and (S)-5a-c.
