Check Digit Verification of cas no

The CAS Registry Mumber 128957-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,5 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128957-80:
(8*1)+(7*2)+(6*8)+(5*9)+(4*5)+(3*7)+(2*8)+(1*0)=172
172 % 10 = 2
So 128957-80-2 is a valid CAS Registry Number.
