Check Digit Verification of cas no

The CAS Registry Mumber 128643-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,4 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128643-89:
(8*1)+(7*2)+(6*8)+(5*6)+(4*4)+(3*3)+(2*8)+(1*9)=150
150 % 10 = 0
So 128643-89-0 is a valid CAS Registry Number.
