Check Digit Verification of cas no

The CAS Registry Mumber 108710-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,7,1 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108710-70:
(8*1)+(7*0)+(6*8)+(5*7)+(4*1)+(3*0)+(2*7)+(1*0)=109
109 % 10 = 9
So 108710-70-9 is a valid CAS Registry Number.
