Check Digit Verification of cas no

The CAS Registry Mumber 214215-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,2,1 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 214215-29:
(8*2)+(7*1)+(6*4)+(5*2)+(4*1)+(3*5)+(2*2)+(1*9)=89
89 % 10 = 9
So 214215-29-9 is a valid CAS Registry Number.

Stereoselective synthesis of racemic α-amino-acid derivatives with a β-lactam skeleton: Application of the Staudinger reaction to chiral imines of methyl glyoxylate

Barreau, Michel,Commercon, Alain,Mignani, Serge,Mouysset, Dominique,Perfetti, Patricia,Stella, Lucien

, p. 11501 - 11516 (2007/10/03)

Selected imines of methyl glyoxylate act as good partners in the Staudinger cycloaddition reaction with a series of substituted ketenes. The cis stereoselectivity is almost complete with electron-donor substituted ketenes, but the asymmetric induction is low when imines derived from chiral l-aryl-ethylamines are used.
