Check Digit Verification of cas no

The CAS Registry Mumber 128500-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,0 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128500-20:
(8*1)+(7*2)+(6*8)+(5*5)+(4*0)+(3*0)+(2*2)+(1*0)=99
99 % 10 = 9
So 128500-20-9 is a valid CAS Registry Number.
