Check Digit Verification of cas no

The CAS Registry Mumber 1042989-68-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,9,8 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1042989-68:
(9*1)+(8*0)+(7*4)+(6*2)+(5*9)+(4*8)+(3*9)+(2*6)+(1*8)=173
173 % 10 = 3
So 1042989-68-3 is a valid CAS Registry Number.
