Check Digit Verification of cas no

The CAS Registry Mumber 1245504-79-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,5,0 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1245504-79:
(9*1)+(8*2)+(7*4)+(6*5)+(5*5)+(4*0)+(3*4)+(2*7)+(1*9)=143
143 % 10 = 3
So 1245504-79-3 is a valid CAS Registry Number.

One-pot synthesis of 2,4,5-trisubstituted 1,2,3-triazoles through the cascade reactions of acid chlorides, terminal acetylenes, sodium azide and aryl halides

Liu, Xiang,Li, Jihui,Chen, Baohua

supporting information, p. 965 - 968 (2013/06/27)

An efficient one-pot reaction of acid chlorides, terminal acetylenes, sodium azide and aryl halides is developed for the regioselective synthesis of 2,4,5-trisubstituted 1,2,3-triazoles. The method is general, convenient, eco-friendly, atom-economical, an

Metal- and base-free three-component reaction of ynones, sodium azide, and Alkyl Halides: Highly regioselective synthesis of 2,4,5-trisubstituted 1,2,3- NH -triazoles

Li, Jihui,Zhang, Yuanqing,Wang, Dong,Wang, Wen,Gao, Tingting,Wang, Lu,Li, Jiting,Huang, Guosheng,Chen, Baohua

supporting information; experimental part, p. 1617 - 1622 (2010/09/05)

A base- and metal-free three-component reaction of ynones, sodium azide, and alkyl halides is developed for the regioselective synthesis of 2,4,5-trisubstituted-1,2,3-triazoles. The method is general, convenient, environmentally benign, atom-economical, and high-yielding.
