Check Digit Verification of cas no

The CAS Registry Mumber 71518-68-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,5,1 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71518-68:
(7*7)+(6*1)+(5*5)+(4*1)+(3*8)+(2*6)+(1*8)=128
128 % 10 = 8
So 71518-68-8 is a valid CAS Registry Number.
