Check Digit Verification of cas no

The CAS Registry Mumber 1044239-12-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,4,2,3 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1044239-12:
(9*1)+(8*0)+(7*4)+(6*4)+(5*2)+(4*3)+(3*9)+(2*1)+(1*2)=114
114 % 10 = 4
So 1044239-12-4 is a valid CAS Registry Number.

Ce(III)-catalyzed highly efficient synthesis of pyridyl benzamides from aminopyridines and nitroolefins without external oxidants

Chen, Zhengwang,Wen, Xiaowei,Qian, Yiping,Liang, Pei,Liu, Botao,Ye, Min

supporting information, p. 1247 - 1251 (2018/03/06)

An efficient synthesis of a variety of pyridyl benzamides from 2-aminopyridines and nitroolefins is described. This rare-earth-metal-catalyzed reaction provides the corresponding products with broad substrate scope in moderate to excellent yields, in the absence of additives and external oxidants. Water is used as the source of the carbonyl oxygen atom in pyridyl benzamides. Furthermore, 2-substituted oxazolo[4,5-b]pyridines are formed in good yields under the standard conditions when 2-aminopyridin-3-ols are used as the substrates.
