Check Digit Verification of cas no

The CAS Registry Mumber 73156-68-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,5 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73156-68:
(7*7)+(6*3)+(5*1)+(4*5)+(3*6)+(2*6)+(1*8)=130
130 % 10 = 0
So 73156-68-0 is a valid CAS Registry Number.
