Check Digit Verification of cas no

The CAS Registry Mumber 1289502-08-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,9,5,0 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1289502-08:
(9*1)+(8*2)+(7*8)+(6*9)+(5*5)+(4*0)+(3*2)+(2*0)+(1*8)=174
174 % 10 = 4
So 1289502-08-4 is a valid CAS Registry Number.
