Check Digit Verification of cas no

The CAS Registry Mumber 903-21-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,0 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 903-21:
(5*9)+(4*0)+(3*3)+(2*2)+(1*1)=59
59 % 10 = 9
So 903-21-9 is a valid CAS Registry Number.
