Check Digit Verification of cas no

The CAS Registry Mumber 502698-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,6,9 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 502698-23:
(8*5)+(7*0)+(6*2)+(5*6)+(4*9)+(3*8)+(2*2)+(1*3)=149
149 % 10 = 9
So 502698-23-9 is a valid CAS Registry Number.
