Check Digit Verification of cas no

The CAS Registry Mumber 496845-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,6,8,4 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 496845-07:
(8*4)+(7*9)+(6*6)+(5*8)+(4*4)+(3*5)+(2*0)+(1*7)=209
209 % 10 = 9
So 496845-07-9 is a valid CAS Registry Number.
