Check Digit Verification of cas no

The CAS Registry Mumber 202071-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,0,7 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 202071-97:
(8*2)+(7*0)+(6*2)+(5*0)+(4*7)+(3*1)+(2*9)+(1*7)=84
84 % 10 = 4
So 202071-97-4 is a valid CAS Registry Number.

Practical enantioselective synthesis of β-substituted-β-amino esters

Awasthi, Alok K.,Boys, Mark L.,Cain-Janicki, Kimberly J.,Colson, Pierre-Jean,Doubleday, Wendel W.,Duran, Joseph E.,Farid, Payman N.

, p. 5387 - 5397 (2007/10/03)

A practical, large-scale synthesis of a β-amino ester 1 was developed. A chiral imine derived from (S)-phenylglycinol and 3-trimethylsilylpropanal was coupled with the Reformatsky reagent 3 with high diastereoselectivity (de > 98%) to give (SS)-4a as the
