Check Digit Verification of cas no

The CAS Registry Mumber 85809-21-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,8,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 85809-21:
(7*8)+(6*5)+(5*8)+(4*0)+(3*9)+(2*2)+(1*1)=158
158 % 10 = 8
So 85809-21-8 is a valid CAS Registry Number.

NUCLEOPHILIC CLEAVAGE OF 2,2-DIMETHYLAZIRIDINES: COMPETITION BETWEEN SN2 AND POSTULATED "SET" MECHANISM.

Stamm, H.,Assithianakis, P.,Buchholz, B.,Weiss, R.

, p. 5021 - 5024 (2007/10/02)

Regioselectivity of nucleophilic attack on 2,2-dimethylaziridines depends on the degree of leaving group activation: in highly activated aziridines it occures at the methylene carbon and in less activated at the tertiary carbon.This latter abnormal ring opening is explained by an SET mechanism.
