Check Digit Verification of cas no
The CAS Registry Mumber 57977-72-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,7 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57977-72:
(7*5)+(6*7)+(5*9)+(4*7)+(3*7)+(2*7)+(1*2)=187
187 % 10 = 7
So 57977-72-7 is a valid CAS Registry Number.

Boehme, Horst,Sutoyo, Paulus
, p. 1671 - 1674 (2007/10/02)
Deprotonation of chloromethyleniminium chlorides (1, 13) leads to cis-trans-isomeres 1,2-diamino-1,2-dichloro-ethenes (3a, 3b resp. 14a; 14b); their reactivity is described.
