Check Digit Verification of cas no

The CAS Registry Mumber 887918-18-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,9,1 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 887918-18:
(8*8)+(7*8)+(6*7)+(5*9)+(4*1)+(3*8)+(2*1)+(1*8)=245
245 % 10 = 5
So 887918-18-5 is a valid CAS Registry Number.
