Check Digit Verification of cas no

The CAS Registry Mumber 99990-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,9 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99990-13:
(7*9)+(6*9)+(5*9)+(4*9)+(3*0)+(2*1)+(1*3)=203
203 % 10 = 3
So 99990-13-3 is a valid CAS Registry Number.
