Check Digit Verification of cas no

The CAS Registry Mumber 103626-03-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,6,2 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 103626-03:
(8*1)+(7*0)+(6*3)+(5*6)+(4*2)+(3*6)+(2*0)+(1*3)=85
85 % 10 = 5
So 103626-03-5 is a valid CAS Registry Number.
