Check Digit Verification of cas no

The CAS Registry Mumber 171020-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,0,2 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 171020-80:
(8*1)+(7*7)+(6*1)+(5*0)+(4*2)+(3*0)+(2*8)+(1*0)=87
87 % 10 = 7
So 171020-80-7 is a valid CAS Registry Number.
