Check Digit Verification of cas no

The CAS Registry Mumber 109703-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,0 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109703-75:
(8*1)+(7*0)+(6*9)+(5*7)+(4*0)+(3*3)+(2*7)+(1*5)=125
125 % 10 = 5
So 109703-75-5 is a valid CAS Registry Number.
