Check Digit Verification of cas no

The CAS Registry Mumber 990-83-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 990-83:
(5*9)+(4*9)+(3*0)+(2*8)+(1*3)=100
100 % 10 = 0
So 990-83-0 is a valid CAS Registry Number.
