Check Digit Verification of cas no

The CAS Registry Mumber 321943-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,9,4 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 321943-80:
(8*3)+(7*2)+(6*1)+(5*9)+(4*4)+(3*3)+(2*8)+(1*0)=130
130 % 10 = 0
So 321943-80-0 is a valid CAS Registry Number.

Cu-catalyzed cross-coupling of methyl ketones and pyridin-2-amines for the synthesis of N-(2-pyridyl)-α-ketoamides

Chen, Ali,Guo, Pengfeng,Lin, Haoming,Liu, Xiang,Rao, Chuixiong,Yang, Daji,Yu, Yue

, p. 417 - 421 (2020/11/30)

An efficient copper-catalyzed strategy for the synthesis of α-ketoamides via cross-coupling of methyl ketones and pyridin-2-amines is described. This transformation has provided a simple process for the formation of C?N and C=O bonds to prepare α-ketoamid

Chemodivergent synthesis of: N -(pyridin-2-yl)amides and 3-bromoimidazo[1,2- a] pyridines from α-bromoketones and 2-aminopyridines

Liu, Yanpeng,Lu, Lixue,Zhou, Haipin,Xu, Feijie,Ma, Cong,Huang, Zhangjian,Xu, Jinyi,Xu, Shengtao

, p. 34671 - 34676 (2019/11/13)

N-(Pyridin-2-yl)amides and 3-bromoimidazo[1,2-a]pyridines were synthesized respectively from α-bromoketones and 2-aminopyridine under different reaction conditions. N-(Pyridin-2-yl)amides were formed in toluene via C-C bond cleavage promoted by I2/s

CuI incorporated cobalt ferrite nanoparticles as a magnetically separable catalyst for oxidative amidation reaction

Dutta, Mintu Maan,Talukdar, Hrishikesh,Phukan, Prodeep

, p. 16041 - 16052 (2019/11/13)

A Cu-incorporated magnetic nanocatalyst (CoFe2O4?SiO2-SH-CuI) has been developed by immobilizing CuI on the modified surface of CoFe2O4 magnetic nanoparticles. The surface of the silica coated cobalt
