Check Digit Verification of cas no

The CAS Registry Mumber 128791-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128791-80:
(8*1)+(7*2)+(6*8)+(5*7)+(4*9)+(3*1)+(2*8)+(1*0)=160
160 % 10 = 0
So 128791-80-0 is a valid CAS Registry Number.
