Check Digit Verification of cas no

The CAS Registry Mumber 128459-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,5 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128459-15:
(8*1)+(7*2)+(6*8)+(5*4)+(4*5)+(3*9)+(2*1)+(1*5)=144
144 % 10 = 4
So 128459-15-4 is a valid CAS Registry Number.
