Check Digit Verification of cas no

The CAS Registry Mumber 1404380-73-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,4,3,8 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1404380-73:
(9*1)+(8*4)+(7*0)+(6*4)+(5*3)+(4*8)+(3*0)+(2*7)+(1*3)=129
129 % 10 = 9
So 1404380-73-9 is a valid CAS Registry Number.
