Check Digit Verification of cas no

The CAS Registry Mumber 128590-33-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,9 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128590-33:
(8*1)+(7*2)+(6*8)+(5*5)+(4*9)+(3*0)+(2*3)+(1*3)=140
140 % 10 = 0
So 128590-33-0 is a valid CAS Registry Number.
