Check Digit Verification of cas no

The CAS Registry Mumber 31413-80-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,1 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31413-80:
(7*3)+(6*1)+(5*4)+(4*1)+(3*3)+(2*8)+(1*0)=76
76 % 10 = 6
So 31413-80-6 is a valid CAS Registry Number.

Oxidant-switchable selective synthesis of 2-aminobenzimidazoles via c-h amination/acetoxylation of guanidines

Chi, Yue,Zhang, Wen-Xiong,Xi, Zhenfeng

, p. 6274 - 6277 (2014)

The iodine(III) compound promoted C-H amination and tandem C-H amination/acetoxylation of guanidines are achieved for the first time to provide efficiently 2-aminobenzimidazoles and acetoxyl-substituted 2-aminobenzimidazoles, respectively. The amount and

Eco-friendly strategy: design and synthesis of biologically potent benzimidazole-amine hybrids via visible-light generated oxidative C-H arylamylation of analenic amidines

Siddiqui,Ibad, Farah,Ibad, Afshan,Abdul Waseem, Malik,Watal, Geeta

, p. 5 - 10 (2015/12/23)

An operationally simple visible light mediated intramolecular cyclization of benzimidazole to 2-amino benzimidazole hybrid. The disclosed procedure is rapid and the convenient synthesis of benzimidazole-amine hybrids from easily available substituted cycl

A protocol to 2-aminobenzimidazoles via copper-catalyzed cascade addition and cyclization of o-haloanilines and carbodiimides

Wang, Fei,Cai, Shangjun,Liao, Qian,Xi, Chanjuan

experimental part, p. 3174 - 3180 (2011/06/24)

An efficient strategy for the synthesis of a variety of 2-animobenzimidazole derivatives has been developed. The reaction proceeded from o-haloanilines and carbodiimides via copper(I)-catalyzed domino reaction in the presence of tert-butoxide to afford the corresponding 2-animobenzimidazole derivatives in good to excellent yields. o-Haloanilines could be o-iodoaniline, o-bromoaniline, and o-chloroaniline derivatives. Carbodiimides could be symmetrical and unsymmetrical substrates with aryl or alkyl substituents. The reaction exhibited a good regioselectivity when unsymmetrical carbodiimides were employed.
