Check Digit Verification of cas no

The CAS Registry Mumber 16634-93-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,3 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16634-93:
(7*1)+(6*6)+(5*6)+(4*3)+(3*4)+(2*9)+(1*3)=118
118 % 10 = 8
So 16634-93-8 is a valid CAS Registry Number.
