Check Digit Verification of cas no

The CAS Registry Mumber 99055-08-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,5 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99055-08:
(7*9)+(6*9)+(5*0)+(4*5)+(3*5)+(2*0)+(1*8)=160
160 % 10 = 0
So 99055-08-0 is a valid CAS Registry Number.
