Check Digit Verification of cas no

The CAS Registry Mumber 109429-60-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,2 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109429-60:
(8*1)+(7*0)+(6*9)+(5*4)+(4*2)+(3*9)+(2*6)+(1*0)=129
129 % 10 = 9
So 109429-60-9 is a valid CAS Registry Number.

CONVERSION OF PENICILLIN G INTO CEPHALEXIN EMPLOYING A SECOND-ORDER ASYMMETRIC TRANSFORMATION

Cooper, John,Humber, David C.,Long, Alan G.

, p. 1469 - 1478 (2007/10/02)

2'S- and 2'R- and S- cephalexin, (5b) and (5c) respectively, both available in six stages from penicillin G, have each been converted to the more useful 2'R-isomer (5a) by a base catalysed epimerization and selective crystallization process involving the N-nitrosoimidazolidinyl derivatives (7).
