Ran in:
str = 'Hello World'

output = regexprep(AIS1, '\d\d\d\d$', '')
This will delete the last 4 characters provided they are digits. It does not "delete the last four digits", so it would leave "ABC12345D" unchanged, and likewise it would leave "AB123D45" unchanged where "last four digits" would require "AB1D" as output
