Check Digit Verification of cas no

The CAS Registry Mumber 404588-44-9 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 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 404588-44:
(8*4)+(7*0)+(6*4)+(5*5)+(4*8)+(3*8)+(2*4)+(1*4)=149
149 % 10 = 9
So 404588-44-9 is a valid CAS Registry Number.
