Check Digit Verification of cas no

The CAS Registry Mumber 412945-51-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,2,9,4 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 412945-51:
(8*4)+(7*1)+(6*2)+(5*9)+(4*4)+(3*5)+(2*5)+(1*1)=138
138 % 10 = 8
So 412945-51-8 is a valid CAS Registry Number.

C-phosphorylated N-(trichloroethylidene)sulfonamides: A new type of highly electrophilic imines

Rassukana, Yuliya V.,Onys'ko, Petro P.,Davydova, Kateryna O.,Sinitsa, Anatolii D.

, p. 3643 - 3649 (2007/10/03)

A convenient preparative approach to previously unknown, highly electrophilic C-phosphorylated N-arylsulfonylimines 1, based on fairly readily accessible α-phosphorylated sulfonamides 5, has been developed. Compounds 1 react with trialkyl phosphites or ethyl diphenylphosphinite in the aza-Perkow reaction scheme to give C,N-diphosphorylated N-dichlorovinylsulfonamides 8. On treatment with O- and S-nucleophilic agents (alcohols, thiols, thiophenols), 1 forms addition products 12 and 15, the functionalized derivatives of α-aminophosphonic acids, while interaction between 1 and mercaptoacetic acid proceeds with intramolecular cyclization of the intermediate adduct to produce the novel 2-phosphorylated thiazolidinones 17.
