Check Digit Verification of cas no

The CAS Registry Mumber 1003-18-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,0 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1003-18:
(6*1)+(5*0)+(4*0)+(3*3)+(2*1)+(1*8)=25
25 % 10 = 5
So 1003-18-5 is a valid CAS Registry Number.
