Check Digit Verification of cas no

The CAS Registry Mumber 87417-71-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,1 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87417-71:
(7*8)+(6*7)+(5*4)+(4*1)+(3*7)+(2*7)+(1*1)=158
158 % 10 = 8
So 87417-71-8 is a valid CAS Registry Number.
