Check Digit Verification of cas no

The CAS Registry Mumber 117135-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,3 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 117135-68:
(8*1)+(7*1)+(6*7)+(5*1)+(4*3)+(3*5)+(2*6)+(1*8)=109
109 % 10 = 9
So 117135-68-9 is a valid CAS Registry Number.
