Check Digit Verification of cas no

The CAS Registry Mumber 480439-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,0,4,3 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 480439-44:
(8*4)+(7*8)+(6*0)+(5*4)+(4*3)+(3*9)+(2*4)+(1*4)=159
159 % 10 = 9
So 480439-44-9 is a valid CAS Registry Number.
