Check Digit Verification of cas no

The CAS Registry Mumber 1204421-58-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,4,2 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1204421-58:
(9*1)+(8*2)+(7*0)+(6*4)+(5*4)+(4*2)+(3*1)+(2*5)+(1*8)=98
98 % 10 = 8
So 1204421-58-8 is a valid CAS Registry Number.

Copper(ii)-hydroxide facilitated C-C bond formation: The carboxamido pyridine system: Versus the methylimino pyridine system

Fan, Weibin,Huang, Deguang,Li, Yinghua,Xiang, Shiqun,Xie, Xingkun,Zhang, Zilong

, p. 12189 - 12196 (2020)

A copper(ii)-hydroxide-induced carbon-carbon bond formation reaction is explored with the synthesis of an asymmetric carboxamido-methylimino pyridine Cu(i) complex of [CuI(py(N-CO)(NC-C)ph2Me2)2]- (12). Two imine-methyl groups are coupled to form a bridge

Microwave-promoted syntheses of pyridine carboxamides and tert-carboximides from novel 6-acetylpyridine-2-carboxylic acid

Su, Biyun,Zhao, Jianshe,Zhang, Qunzheng,Qin, Wenlong

experimental part, p. 4429 - 4440 (2010/05/01)

A novel 6-acetylpyridine-2-carboxylic acid (4) was obtained occasionally during the synthesis of asymmetric ethyl 6-acetylpyridine-2-carboxylate (3) from 2,6-dipiclinic acid (1). Compounds 3 and 4 could transform mutually under some specific conditions. T
