Check Digit Verification of cas no

The CAS Registry Mumber 1400634-66-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,6,3 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1400634-66:
(9*1)+(8*4)+(7*0)+(6*0)+(5*6)+(4*3)+(3*4)+(2*6)+(1*6)=113
113 % 10 = 3
So 1400634-66-3 is a valid CAS Registry Number.

Evaluation of electrophilic heteroaromatic substitution: Synthesis of heteroaromatic-fused pyrimidine derivatives via sequential three-component heterocyclization

Wong, Fung Fuh,Huang, Yu-Ying,Chang, Chun-Hsi

, p. 8492 - 8500 (2012)

A new sequential three-component heterocyclization was developed by reacting aromatic and heterocyclic substrates, including aminobenzenes, 1-aminonaphthalene, 2-aminopyrazines, 5-aminopyrazoles, 3-aminopyridine, 5-aminopyrimidine, 5-aminoquinoline, and 8

One-pot synthesis and antiproliferative evaluation of pyrazolo[3,4-d] pyrimidine derivatives

Huang, Yu-Ying,Wang, Li-Ya,Chang, Chun-Hsi,Kuo, Yueh-Hsiung,Kaneko, Kimiyoshi,Takayama, Hiroyuki,Kimura, Masayuki,Juang, Shin-Hun,Wong, Fung Fuh

supporting information, p. 9658 - 9664 (2012/11/07)

An efficient one-pot methodology for the synthesis of pyrazolo[3,4-d] pyrimidines was developed by using 5-aminopyrazoles with formamide in presence of PBr3 as the coupling agent. Among the examples presented in this work, compounds 41 and 54-5
