Check Digit Verification of cas no

The CAS Registry Mumber 1204504-82-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,5,0 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1204504-82:
(9*1)+(8*2)+(7*0)+(6*4)+(5*5)+(4*0)+(3*4)+(2*8)+(1*2)=104
104 % 10 = 4
So 1204504-82-4 is a valid CAS Registry Number.
