Check Digit Verification of cas no

The CAS Registry Mumber 2003-31-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,0 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2003-31:
(6*2)+(5*0)+(4*0)+(3*3)+(2*3)+(1*1)=28
28 % 10 = 8
So 2003-31-8 is a valid CAS Registry Number.
