Check Digit Verification of cas no
The CAS Registry Mumber 6648-13-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,4 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6648-13:
(6*6)+(5*6)+(4*4)+(3*8)+(2*1)+(1*3)=111
111 % 10 = 1
So 6648-13-1 is a valid CAS Registry Number.

REACTION OF 2-AMINOBENZIMIDAZOLE WITH ACETYLENE
Baikalova, L. V.,Domnina, E. S.,Afonin, A. V.
, p. 588 - 589 (2007/10/02)
The reaction of 2-aminobenzimidazole (1) with acetylene under pressure proceeds with the formation of vinyl monomers, corresponding to amine and imine forms, 1-vinyl-2-amino- and 1,3-divinyl-2-iminobenzimidazoles, depending on the reaction conditions. 1,3-Divinyl-2-benzimidazolone was also isolated in aqueous dioxane in addition to the monovinyl derivative of 1.Cyclization of the divinyl derivative of 1 with acetylene preceeds to give 9-vinyl-1,2-dimethylimidazobenzimidazole. Keywords: 2-aminobenzimidazole, acetylene, vinyl monomers.
