Check Digit Verification of cas no

The CAS Registry Mumber 1352820-89-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,8,2 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1352820-89:
(9*1)+(8*3)+(7*5)+(6*2)+(5*8)+(4*2)+(3*0)+(2*8)+(1*9)=153
153 % 10 = 3
So 1352820-89-3 is a valid CAS Registry Number.

Synthesis of a tetracyclic aminobenzimidazole derivative via tandem cyclization of triphenylguanidine

Akamatsu, Yuki,Kamino, Shinichiro,Sawada, Daisuke

, p. 815 - 819 (2019/08/01)

We developed a new reaction for the one-pot synthesis of a fused cyclic compound from triphenylguanidine, which was thought to be tandem cyclization, with a moderate yield. In this reaction, conditions such as the metal reagent, oxidant, solvent, and liga

An efficient and facile synthesis of benzimidazo[1,2-a]benzimidazoles via copper-catalyzed domino addition/double cyclization

Yuan, Guodong,Liu, Haiquan,Gao, Jilong,Xu, Hongjuan,Jiang, Liu,Wang, Xiaoxia,Lv, Xin

, p. 21904 - 21908 (2014/06/23)

A copper-catalyzed synthesis of benzimidazo[1,2-a]benzimidazoles by domino addition/double cyclization of bis-(o-haloaryl)carbodiimides with primary amines was developed. A variety of the desired polycyclic benzimidazoles were efficiently and facilely assembled. Multibonds and polycyclic moieties were directly constructed in one pot. 2-Bromo-2′-iodo-diarylcarbodiimides gave good selectivity. This journal is the Partner Organisations 2014.

Copper-catalyzed domino addition/double cyclization: An approach to polycyclic benzimidazole derivatives

Yuan, Guodong,Liu, Haiquan,Gao, Jilong,Yang, Kangjian,Niu, Qingsheng,Mao, Hui,Wang, Xiaoxia,Lv, Xin

, p. 1749 - 1757 (2014/03/21)

An efficient and versatile method for the assembly of novel polycyclic benzimidazole derivatives has been developed by Cu-catalyzed domino addition/double cyclization reactions. A wide variety of polycyclic benzimidazole derivatives, which might be used as synthetic medicines and functional materials, were successfully assembled from bis-(o-haloaryl) carbodiimides. Unexpected N-methylated benzo[4,5]imidazo[1,2-a]indoles can also be selectively assembled. Multibonds and polycyclic moieties were conveniently formed in one pot during these domino processes.
