Check Digit Verification of cas no

The CAS Registry Mumber 84858-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,5 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84858-89:
(7*8)+(6*4)+(5*8)+(4*5)+(3*8)+(2*8)+(1*9)=189
189 % 10 = 9
So 84858-89-9 is a valid CAS Registry Number.
