Check Digit Verification of cas no

The CAS Registry Mumber 1449762-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,7,6 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1449762-71:
(9*1)+(8*4)+(7*4)+(6*9)+(5*7)+(4*6)+(3*2)+(2*7)+(1*1)=203
203 % 10 = 3
So 1449762-71-3 is a valid CAS Registry Number.

Combinatorial synthesis of pyrrolo[3,2-f]quinoline and pyrrolo[3,2-a] acridine derivatives via a three-component reaction under catalyst-free conditions

Zhou, Yu-Jing,Chen, Dong-Sheng,Li, Yu-Ling,Liu, Yun,Wang, Xiang-Shan

supporting information, p. 498 - 502 (2013/09/24)

A combinatorial synthesis of pyrrolo[3,2-f]quinoline and pyrrolo[3,2-a]acridine derivatives is described as a three-component reaction of aromatic aldehyde, 1H-indol-5-amine, and 1,3-dicarbonyl compounds under catalyst-free conditions. The 1,3-dicarbonyl compounds include 5,5-dimethylcyclohexane-1,3-dione, cyclopentane-1,3-dione, and 2H-indene-1,3-dione. It is interesting that the designed reactions gave aromatized or unaromatized products, which depend on the reaction temperature and reactants of 1,3-dicarbonyl compounds.
