    The following works. I will let you tweak the code further if you need to so I am not doing all your homework ğŸ˜‚

     

    StringMatch = 
VAR NoBlankFreeText =
    SUBSTITUTE ( 'Sample Data'[FreeText], " ", "", 1 )
VAR UpperD =
    FIND ( "D", NoBlankFreeText, 1, BLANK () )
VAR LowerD =
    FIND ( "d", NoBlankFreeText, 1, BLANK () )
VAR PositionD =
    IF ( ISNUMBER ( UpperD ), UpperD, LowerD)
VAR CheckNumbers =
    ISERROR (
        ISNUMBER ( VALUE ( MID ( NoBlankFreeText, PositionD + 1, 5 ) ) )
    )
RETURN 
    IF (
        NOT ( CheckNumbers ),
        MID ( NoBlankFreeText, PositionD, 6),
        "No Match"
    )

Or you can use CONTAINSSTRING function e.g 

MyCalculatedColumn = If(CONTAINSSTRING([TARGETCOLUMN];"searchforthis");TRUE();FALSE())

    I am not sure how this will work when the end goal is "any letter followed by any numbers" when the letter and the numbers could be anything, e.g. it can be "Z 98765" or "b34561" or worse "!@#@!D48202@#!@".

      The letter will always be "D" or "d"
      There may be a space (or may not be) and then 5 numbers between 0 and 9
