Check Digit Verification of cas no

The CAS Registry Mumber 1224635-44-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,4,6,3 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1224635-44:
(9*1)+(8*2)+(7*2)+(6*4)+(5*6)+(4*3)+(3*5)+(2*4)+(1*4)=132
132 % 10 = 2
So 1224635-44-2 is a valid CAS Registry Number.

supporting information; experimental part, p. 368 - 372 (2010/06/11)

Aniline-substituted diethynylarenes, which are readily synthesized through Sonogashira coupling reactions from commercially available 1,2-dihaloarenes, directly produce aryl- and heteroaryl-annulated [a]carbazoles by the gold-catalyzed intramolecular casc
