Check Digit Verification of cas no

The CAS Registry Mumber 98589-66-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,8 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 98589-66:
(7*9)+(6*8)+(5*5)+(4*8)+(3*9)+(2*6)+(1*6)=213
213 % 10 = 3
So 98589-66-3 is a valid CAS Registry Number.
