Check Digit Verification of cas no

The CAS Registry Mumber 1204429-63-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,4,2 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1204429-63:
(9*1)+(8*2)+(7*0)+(6*4)+(5*4)+(4*2)+(3*9)+(2*6)+(1*3)=119
119 % 10 = 9
So 1204429-63-9 is a valid CAS Registry Number.
