Check Digit Verification of cas no

The CAS Registry Mumber 289041-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,0,4 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 289041-20:
(8*2)+(7*8)+(6*9)+(5*0)+(4*4)+(3*1)+(2*2)+(1*0)=149
149 % 10 = 9
So 289041-20-9 is a valid CAS Registry Number.
