Check Digit Verification of cas no

The CAS Registry Mumber 1417819-44-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,8,1 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1417819-44:
(9*1)+(8*4)+(7*1)+(6*7)+(5*8)+(4*1)+(3*9)+(2*4)+(1*4)=173
173 % 10 = 3
So 1417819-44-3 is a valid CAS Registry Number.

Nucleophilic addition of benzimidazoles to alkynyl bromides/palladium- catalyzed intramolecular C-H vinylation: Synthesis of benzo[4,5]imidazo[2,1-a] isoquinolines

Peng, Jinsong,Shang, Guoning,Chen, Chunxia,Miao, Zhongshuo,Li, Bin

, p. 1242 - 1248 (2013)

An efficient "one-pot" route for the synthesis of benzo[4,5]imidazo[2,1-a] isoquinolines has been developed via nucleophilic addition of 2-aryl benzimidazoles to alkynyl bromides and subsequent palladium-catalyzed intramolecular C-H vinylation.
