Check Digit Verification of cas no

The CAS Registry Mumber 191794-08-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,7,9 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 191794-08:
(8*1)+(7*9)+(6*1)+(5*7)+(4*9)+(3*4)+(2*0)+(1*8)=168
168 % 10 = 8
So 191794-08-8 is a valid CAS Registry Number.

Ambident heterocyclic reactivity: Intramolecular alkylations of 2,4-disubstituted benzimidazoles

Haque, M. Rezaul,Rasmussen, Malcolm

, p. 6937 - 6958 (2007/10/03)

Alkali induced intramolecular cyclizations of 2-(3-chloropropyl)- and 2-(4-chlorobutyl)-4-substituted benzimidazoles bearing 4-nitro-, 4-amino-, and 4-methyl groups show enhanced N3/N1 regioselectivity compared to the corresponding intermolecular alkylations with 1-chlorobutane. The observed N1:N3 cyclization ratios vary from 94:6 to 10:90, with the largest preference for reaction at the 'congested' N3-site occurring in the 5-membered ring formation. In contrast, related base induced reactions of (2-benzimidazolyl)methyl chloroacetate and 3-(2-benzimidazolyl)propyl chloroacetate give excellent yields of macrocyclic dimeric systems. These results are interpreted as involving interplay between electrostatic field, through-bond electronic, and steric approach control factors within variable geometry S(N)2 transition state structures. Calculations (AMI and molecular mechanics) on these systems and conformational analysis of the expected transition states for the intramolecular cyclizations do not support any appreciable use of out-of-plane approach trajectories for these heterocyclic N- alkylation reactions.
