Check Digit Verification of cas no

The CAS Registry Mumber 99761-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,6 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99761-80:
(7*9)+(6*9)+(5*7)+(4*6)+(3*1)+(2*8)+(1*0)=195
195 % 10 = 5
So 99761-80-5 is a valid CAS Registry Number.
