Check Digit Verification of cas no

The CAS Registry Mumber 935549-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,5,5,4 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 935549-58:
(8*9)+(7*3)+(6*5)+(5*5)+(4*4)+(3*9)+(2*5)+(1*8)=209
209 % 10 = 9
So 935549-58-9 is a valid CAS Registry Number.
