Check Digit Verification of cas no

The CAS Registry Mumber 203-00-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203-00:
(5*2)+(4*0)+(3*3)+(2*0)+(1*0)=19
19 % 10 = 9
So 203-00-9 is a valid CAS Registry Number.
