Check Digit Verification of cas no

The CAS Registry Mumber 111490-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,9 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111490-89:
(8*1)+(7*1)+(6*1)+(5*4)+(4*9)+(3*0)+(2*8)+(1*9)=102
102 % 10 = 2
So 111490-89-2 is a valid CAS Registry Number.

DISPLACEMENT WITH NITROGEN NUCLEOPHILES AT C-3' of 7-AMINOCEPHALOSPORANIC ACID AND DERIVATIVES PROMOTED BY TRIALKYLSILYL TRIFLUOROMETHANESULPHONATES

Acton, David G.,Rogers, Kevin J.,Poyser, Philip J.

, p. 657 - 662 (2007/10/02)

Replacement of a 3'-acetate group of a cephem by an alkylamino group can be mediated by trialkylsilyl trifluoromethanesulphonates in dichloromethane or acetonitrile inter alia.Comparable yields to the more usual 3'-iodo routes have been achieved, using a
