Check Digit Verification of cas no

The CAS Registry Mumber 174502-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,5,0 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 174502-23:
(8*1)+(7*7)+(6*4)+(5*5)+(4*0)+(3*2)+(2*2)+(1*3)=119
119 % 10 = 9
So 174502-23-9 is a valid CAS Registry Number.

supporting information, p. 606 - 609 (2013/04/23)

It was demonstrated experimentally that nonplanar iron porphyrins can be induced to undergo a conversion in their electronic configuration to form a cross-hybrid transition by compressing the macrocyclic core size for the central metal ion. A series of mo
