Check Digit Verification of cas no

The CAS Registry Mumber 857591-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,5,9 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 857591-04:
(8*8)+(7*5)+(6*7)+(5*5)+(4*9)+(3*1)+(2*0)+(1*4)=209
209 % 10 = 9
So 857591-04-9 is a valid CAS Registry Number.
