Check Digit Verification of cas no

The CAS Registry Mumber 1417542-64-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,5,4 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1417542-64:
(9*1)+(8*4)+(7*1)+(6*7)+(5*5)+(4*4)+(3*2)+(2*6)+(1*4)=153
153 % 10 = 3
So 1417542-64-3 is a valid CAS Registry Number.

Copper-catalyzed click synthesis of functionalized 1,2,3-triazoles with 3,4-dihydropyrimidinone or amide group via a one-pot four-component reaction

Quan, Zheng-Jun,Xu, Qiong,Zhang, Zhang,Da, Yu-Xia,Wang, Xi-Cun

, p. 881 - 887 (2013/07/27)

A Cu (I) generated in situ from Cu(OAc)2·H 2O/sodium ascorbate catalyzed one-pot multicomponent reaction for the synthesis of a series of N-functionalized 1,2,3-triazoles with 3,4-dihydropyrimidione from 3,4-dihydropyrimidiones, paraformaldehyde, sodium azide and alkynes is described. Remarkably N-functionalized 1,2,3-triazoles with amide were prepared by this method. This procedure eliminates the need to handle organic halides or organic azides, as they are generated in situ, making this already powerful click process even more user-friendly and safe.
