Check Digit Verification of cas no

The CAS Registry Mumber 1646540-73-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,6,5,4 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1646540-73:
(9*1)+(8*6)+(7*4)+(6*6)+(5*5)+(4*4)+(3*0)+(2*7)+(1*3)=179
179 % 10 = 9
So 1646540-73-9 is a valid CAS Registry Number.

Catalyst-dependent divergent synthesis of pyrroles from 3-alkynyl imine derivatives: A noncarbonylative and carbonylative approach

Chen, Gen-Qiang,Zhang, Xiao-Nan,Wei, Yin,Tang, Xiang-Ying,Shi, Min

supporting information, p. 8492 - 8497 (2014/08/18)

A novel Ru0- and RhI-catalyzed noncarbonylative and carbonylative cycloisomerization of readily available 3-alkynyl imine derivatives has been developed to provide 3,4-fused or nonfused pyrrole derivatives efficiently in moderate to
