Check Digit Verification of cas no

The CAS Registry Mumber 502493-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,4,9 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 502493-99:
(8*5)+(7*0)+(6*2)+(5*4)+(4*9)+(3*3)+(2*9)+(1*9)=144
144 % 10 = 4
So 502493-99-4 is a valid CAS Registry Number.
