Check Digit Verification of cas no

The CAS Registry Mumber 71165-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,6 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71165-75:
(7*7)+(6*1)+(5*1)+(4*6)+(3*5)+(2*7)+(1*5)=118
118 % 10 = 8
So 71165-75-8 is a valid CAS Registry Number.
