Check Digit Verification of cas no

The CAS Registry Mumber 289503-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,5,0 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 289503-63:
(8*2)+(7*8)+(6*9)+(5*5)+(4*0)+(3*3)+(2*6)+(1*3)=175
175 % 10 = 5
So 289503-63-5 is a valid CAS Registry Number.
