Check Digit Verification of cas no

The CAS Registry Mumber 128190-78-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,9 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128190-78:
(8*1)+(7*2)+(6*8)+(5*1)+(4*9)+(3*0)+(2*7)+(1*8)=133
133 % 10 = 3
So 128190-78-3 is a valid CAS Registry Number.
