Rename certain files within a folder

Maikel 6

Hello, i want a Batch that finds Files in a Folder that are called master_example. After they found all of them, they should rename ONLY the part "master" into a specific string of numbers (example:657432).
How can i do that?

**Start of script **
setlocal enableDelayedExpansion
for %%F in (master*.txt) do (
set "name=%%F"
ren "!name!" "!name:master=123456!"
)

**End of Script **
