Check Digit Verification of cas no

The CAS Registry Mumber 1044552-08-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,4,5,5 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1044552-08:
(9*1)+(8*0)+(7*4)+(6*4)+(5*5)+(4*5)+(3*2)+(2*0)+(1*8)=120
120 % 10 = 0
So 1044552-08-0 is a valid CAS Registry Number.
