Check Digit Verification of cas no

The CAS Registry Mumber 404589-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,5,8 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 404589-20:
(8*4)+(7*0)+(6*4)+(5*5)+(4*8)+(3*9)+(2*2)+(1*0)=144
144 % 10 = 4
So 404589-20-4 is a valid CAS Registry Number.
