Check Digit Verification of cas no

The CAS Registry Mumber 90663-07-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,6 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90663-07:
(7*9)+(6*0)+(5*6)+(4*6)+(3*3)+(2*0)+(1*7)=133
133 % 10 = 3
So 90663-07-3 is a valid CAS Registry Number.
