Check Digit Verification of cas no

The CAS Registry Mumber 103603-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,6,0 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 103603-83:
(8*1)+(7*0)+(6*3)+(5*6)+(4*0)+(3*3)+(2*8)+(1*3)=84
84 % 10 = 4
So 103603-83-4 is a valid CAS Registry Number.
