Removing last character of CELL if it's a (number / space / comma)

Dear Excel community,

I'm facing a problem which I can't solve after trying a lot of different options. I attached an excel file as an example.

Following is the problem:

I'm using a column with in each cell a product description including some article numbers. I now want to remove all these article numbers since they're outdated.

For example:

This is a product description, for product A 4353434323, 42354252435, 324325432, 56003324, 3445435

This is a product description, for product B 723487234, 443563214

I need to have these article numbers removed, the problem is, some descriptions have 2 article numbers, some 4 or some even more than 10.

So my logic would be something like: Remove last character if it's equal to a number / space / comma. In that way it would strip out everything except the description itself. I thought in this direction: =IF(RIGHT(A1,1)=" ", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", ",",LEFT(A1,LEN(A1)-1),A1) but that obviously doesn't work.

In the example file is some test data (5 in total) in reality we're talking about more than 2000+ descriptions. So deleting by hand wasn't my first choice as you probably can imagine.

I'm probably overthinking once again. Could you help me?

Many thanks in advance.
