Check Digit Verification of cas no

The CAS Registry Mumber 1621432-61-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,4,3 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1621432-61:
(9*1)+(8*6)+(7*2)+(6*1)+(5*4)+(4*3)+(3*2)+(2*6)+(1*1)=128
128 % 10 = 8
So 1621432-61-8 is a valid CAS Registry Number.

An expeditious microwave assisted one-pot sequential route to pyrido fused imidazo[4,5-c] quinolines in green media

Rao, Ramdas Nishanth,Chanda, Kaushik

, p. 3280 - 3289 (2021/02/26)

An expeditious microwave assisted one-pot sequential route to synthesize pyrido fused imidazo[4,5-c]quinolinesviathe Pictet-Spengler cyclization strategy has been developed. In this study, substituted 2-amino pyridines are condensed with 2-bromo-2′-nitroa

One-pot sequential reactions featuring a copper-catalyzed amination leading to pyrido[2′,1′:2,3]imidazo[4,5-c]quinolines and dihydropyrido[2′,1′:2,3]imidazo[4,5-c]quinolines

Fan, Xue-Sen,Zhang, Ju,Li, Bin,Zhang, Xin-Ying

, p. 1281 - 1285 (2015/06/08)

Tetracyclic skeletons combining an imidazo[1,2-a]pyridine moiety with a quinoline framework such as pyrido[2′,1′:2,3]imidazo[4,5-b]quinoline are stimulating increasing interests since they are close isosteres of a series of powerful antiproliferative comp
