Check Digit Verification of cas no

The CAS Registry Mumber 54889-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,8 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 54889-42:
(7*5)+(6*4)+(5*8)+(4*8)+(3*9)+(2*4)+(1*2)=168
168 % 10 = 8
So 54889-42-8 is a valid CAS Registry Number.
