Check Digit Verification of cas no

The CAS Registry Mumber 1428380-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,3,8 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1428380-91:
(9*1)+(8*4)+(7*2)+(6*8)+(5*3)+(4*8)+(3*0)+(2*9)+(1*1)=169
169 % 10 = 9
So 1428380-91-9 is a valid CAS Registry Number.

Acid-catalyzed synthesis of imidazole derivatives via N-phenylbenzimidamides and sulfoxonium ylides cyclization

Tian, Yuan,Qin, Mingda,Yang, Xueying,Zhang, Xueguo,Liu, Yafeng,Guo, Xin,Chen, Baohua

, p. 2817 - 2823 (2019/04/13)

A straightforward method to synthesize imidazole derivatives from amidines and sulfoxonium ylides catalyzed by acids is reported in this study. Specifically, catalyzed by trifluoroacetic acid in DCE solvents can improve synthesis efficiency under metal-fr
