Check Digit Verification of cas no

The CAS Registry Mumber 95502-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,5,0 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 95502-21:
(7*9)+(6*5)+(5*5)+(4*0)+(3*2)+(2*2)+(1*1)=129
129 % 10 = 9
So 95502-21-9 is a valid CAS Registry Number.
