Check Digit Verification of cas no

The CAS Registry Mumber 1453813-81-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,3,8,1 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1453813-81:
(9*1)+(8*4)+(7*5)+(6*3)+(5*8)+(4*1)+(3*3)+(2*8)+(1*1)=164
164 % 10 = 4
So 1453813-81-4 is a valid CAS Registry Number.

The synthesis of 2-(Arylthio)arylcyanamides via copper-catalyzed domino intermolecular c-s cross-coupling reaction of 2-aminobenzothiazoles with aryl iodides

Shao, Yin-Lin,Zhang, Xiao-Hong,Han, Jiang-Sheng,Zhong, Ping

, p. 1137 - 1146 (2013/09/23)

A series of 2-(arylthio)arylcyanamide derivatives were obtained in excellent yields via a copper-catalyzed domino C-S cross-coupling of 2-aminobenzothiazoles with aryl iodides. This reaction occurred via an intermolecular C-S bond formation, associated with C-S bond cleavage, followed by an intermolecular S-arylation under ligand-free conditions. Their structures were unambiguously determined by the analytic tools, such as HRMS, 1H, and 13C NMR analysis.
