Check Digit Verification of cas no

The CAS Registry Mumber 77375-17-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,7 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77375-17:
(7*7)+(6*7)+(5*3)+(4*7)+(3*5)+(2*1)+(1*7)=158
158 % 10 = 8
So 77375-17-8 is a valid CAS Registry Number.
