Check Digit Verification of cas no

The CAS Registry Mumber 1228041-29-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,0,4 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1228041-29:
(9*1)+(8*2)+(7*2)+(6*8)+(5*0)+(4*4)+(3*1)+(2*2)+(1*9)=119
119 % 10 = 9
So 1228041-29-9 is a valid CAS Registry Number.
