I assumed your entire string was = 'ABCD-181888  BCDE-234'. If ever you may have numerics interspersed in your string, you'll need a user defined function:

CREATE FUNCTION dbo.udf_GetNumeric (
    @strAlphaNumeric    varchar(255)
RETURNS varchar(255)
    DECLARE @intAlpha INT
    SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric)
    WHILE @intAlpha > 0
        SET @strAlphaNumeric = STUFF(@strAlphaNumeric, @intAlpha, 1, '' )
        SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric )
    RETURN ISNULL(@strAlphaNumeric, 0)

Then you can execute it similar to the following:

DECLARE @TestString varchar(255)
SET @TestString = 'ABCD-181888  BCDE-234'
SELECT  @TestString     AS TestString,
        dbo.udf_GetNumeric(@TestString) AS Converted
