Check Digit Verification of cas no

The CAS Registry Mumber 99680-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,8 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99680-08:
(7*9)+(6*9)+(5*6)+(4*8)+(3*0)+(2*0)+(1*8)=187
187 % 10 = 7
So 99680-08-7 is a valid CAS Registry Number.
