Check Digit Verification of cas no

The CAS Registry Mumber 117109-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,0 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 117109-80:
(8*1)+(7*1)+(6*7)+(5*1)+(4*0)+(3*9)+(2*8)+(1*0)=105
105 % 10 = 5
So 117109-80-5 is a valid CAS Registry Number.
