Check Digit Verification of cas no

The CAS Registry Mumber 1020409-45-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,4,0 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1020409-45:
(9*1)+(8*0)+(7*2)+(6*0)+(5*4)+(4*0)+(3*9)+(2*4)+(1*5)=83
83 % 10 = 3
So 1020409-45-3 is a valid CAS Registry Number.
