Check Digit Verification of cas no

The CAS Registry Mumber 123003-83-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,0,0 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 123003-83:
(8*1)+(7*2)+(6*3)+(5*0)+(4*0)+(3*3)+(2*8)+(1*3)=68
68 % 10 = 8
So 123003-83-8 is a valid CAS Registry Number.
