Check Digit Verification of cas no

The CAS Registry Mumber 1034024-34-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,4,0,2 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1034024-34:
(9*1)+(8*0)+(7*3)+(6*4)+(5*0)+(4*2)+(3*4)+(2*3)+(1*4)=84
84 % 10 = 4
So 1034024-34-4 is a valid CAS Registry Number.
