Check Digit Verification of cas no

The CAS Registry Mumber 136943-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,4 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136943-91:
(8*1)+(7*3)+(6*6)+(5*9)+(4*4)+(3*3)+(2*9)+(1*1)=154
154 % 10 = 4
So 136943-91-4 is a valid CAS Registry Number.

Studies on sulfenamides. XIII. Reaction of 2-nitrobenzenesulfenanilides with N-bromosuccinimide

Michida,Mizuhara,Sayo

, p. 1857 - 1859 (2007/10/02)

The reaction of N-alkyl 2-nitrobenzenesulfenanilide (1a-3a) with N-bromosuccinimide (NBS) gave the corresponding monobrominated 2-nitrobenzenesulfenanilides (1b-3b) in good yields. The initial step of this reaction is the attack of NBS on the nitrogen atom of 1a-3a. The intermediate of this reaction is considered to be a cation radical of the sulfenanilides. A similar reaction of N-unsubstituted 2-nitrobenzenesulfenanilides (5a-10a) with NBS gave mono- or di-brominated 2-nitrobenzenesulfenanilides in low yields.
