Check Digit Verification of cas no

The CAS Registry Mumber 87768-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,6 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87768-87:
(7*8)+(6*7)+(5*7)+(4*6)+(3*8)+(2*8)+(1*7)=204
204 % 10 = 4
So 87768-87-4 is a valid CAS Registry Number.
