MATLAB: Perform "For-loop or IF-statement" only for specific character arrays

I have 60 different character arrays (Book01, Book02, ..., Book60). (For example Book01 is a 1x202040 char.). I want to do a certain procedure only for Book045 until Book58.

How do I write an IF-statement or FOR-loop, so that the procedure is only performed for character arrays Book045 until Book58? For example:

Book05  % Inserted Array for test

if Book45|Book46|Book47|Book48|Book49|Book50|Book51|Book52|Book53|Book54|Book54|Book56|Book57|Book58 % If inserted array is Book45-58     
   My Procedure      
else
   No Procedure
end

Thanks
