try this:
@ECHO OFF &SETLOCAL ENABLEDELAYEDEXPANSION
SET "teststring=abcDEFG1234ABSdefh"
FOR %%a IN (
a b c d e f g h i j k l m n o p q r s t u v w x y z
) DO (
SET "teststring=!teststring:%%a=!"
)
ECHO %teststring%
Note: this doesn't work with special characters, eg.: <>&|!^

If your string always has the form string-hyphen-number-hyphen-string (e.g. foo-23-bar, some-205-orother, …) you could do something like this:
@echo off
setlocal
set "string=foo-23-bar"
for /f "tokens=2 delims=-" %%n in ("%string%") do set "num=%%n"
echo %num%
