Searching for a numbers from right within a text string

Hi, I have a list of notes that contain text and numbers within a cell. I need a formula if possible that searches from the right of the cell and then returns the all the numbers.

e.g.

1.Inter 2. Juventus 3. R0ma 4.Cagliari formula result 4
3. Politics;5 National, 7. Biology formula result 7
19geographic formula result 19

The Result is extract a numbers within text cell from right.
I can not use text to columns as they data is not consistant.

Also worth noting is that the notes vary from 1 digit to 9 digits long.

Any help would be great
