Check Digit Verification of cas no

The CAS Registry Mumber 117901-71-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,0 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117901-71:
(8*1)+(7*1)+(6*7)+(5*9)+(4*0)+(3*1)+(2*7)+(1*1)=120
120 % 10 = 0
So 117901-71-0 is a valid CAS Registry Number.
