The key here is to use "awk" to extract the filename rather than "cut" because when the day of the month in the timestamp is a single digit the filename will be in a different position.

Code:
0ne way:
cat myfile.txt | awk '{print $9}' | cut -c4-8 | while read number
do
       echo "${number}"
done

Or if you prefer redirection to cat:
cat myfile.txt | awk '{print $9}' | cut -c4-8 | while read number
do
       echo "${number}"
done < myfile.txt

Or we could read the file directly with "awk":
awk '{print $9}' myfile.txt| cut -c4-8 | while read number
do
       echo "${number}"
done
