Check Digit Verification of cas no

The CAS Registry Mumber 103897-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,8,9 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103897-30:
(8*1)+(7*0)+(6*3)+(5*8)+(4*9)+(3*7)+(2*3)+(1*0)=129
129 % 10 = 9
So 103897-30-9 is a valid CAS Registry Number.
