Check Digit Verification of cas no

The CAS Registry Mumber 89889-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,8 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89889-91:
(7*8)+(6*9)+(5*8)+(4*8)+(3*9)+(2*9)+(1*1)=228
228 % 10 = 8
So 89889-91-8 is a valid CAS Registry Number.
