Check Digit Verification of cas no

The CAS Registry Mumber 10003-11-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,0 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10003-11:
(7*1)+(6*0)+(5*0)+(4*0)+(3*3)+(2*1)+(1*1)=19
19 % 10 = 9
So 10003-11-9 is a valid CAS Registry Number.
