Check Digit Verification of cas no

The CAS Registry Mumber 66365-87-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,6 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66365-87:
(7*6)+(6*6)+(5*3)+(4*6)+(3*5)+(2*8)+(1*7)=155
155 % 10 = 5
So 66365-87-5 is a valid CAS Registry Number.
