Check Digit Verification of cas no

The CAS Registry Mumber 204990-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,9,9 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 204990-52:
(8*2)+(7*0)+(6*4)+(5*9)+(4*9)+(3*0)+(2*5)+(1*2)=133
133 % 10 = 3
So 204990-52-3 is a valid CAS Registry Number.
