Check Digit Verification of cas no

The CAS Registry Mumber 87428-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,2 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87428-86:
(7*8)+(6*7)+(5*4)+(4*2)+(3*8)+(2*8)+(1*6)=172
172 % 10 = 2
So 87428-86-2 is a valid CAS Registry Number.
