Check Digit Verification of cas no

The CAS Registry Mumber 78173-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,7 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78173-41:
(7*7)+(6*8)+(5*1)+(4*7)+(3*3)+(2*4)+(1*1)=148
148 % 10 = 8
So 78173-41-8 is a valid CAS Registry Number.
