Check Digit Verification of cas no

The CAS Registry Mumber 490-03-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 490-03:
(5*4)+(4*9)+(3*0)+(2*0)+(1*3)=59
59 % 10 = 9
So 490-03-9 is a valid CAS Registry Number.
