Check Digit Verification of cas no

The CAS Registry Mumber 771564-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,1,5,6 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 771564-49:
(8*7)+(7*7)+(6*1)+(5*5)+(4*6)+(3*4)+(2*4)+(1*9)=189
189 % 10 = 9
So 771564-49-9 is a valid CAS Registry Number.

Design, multicomponent synthesis, and bioactivities of novel neonicotinoid analogues with 1,4-dihydropyridine scaffold

Zhang, Wenwen,Yang, Xiaobao,Chen, Weidong,Xu, Xiaoyong,Li, Lu,Zhai, Hongbin,Li, Zhong

experimental part, p. 2741 - 2745 (2011/07/31)

Novel neonicotinoid analogues bearing a 1,4-dihydropridine scaffold were designed and synthesized by multicomponent reactions (MCRs) to enhance π-π stacking. The synthesized compounds were identified by 1H NMR, 13C NMR, high-resoluti
