    asdfasf-ABCDE-asdfasdfsfasf
    ss-TREWQ-asdfasfsf

    If we can safely assume that there are exactly two dashes in the entire column, AND, that they are always going to contain exactly 5 characters in between them, then this should work:
    SELECT SUBSTRING(CI_NUM, CHARINDEX('-', CI_NUM) + 1, 5) AS CI_NUM_MIDDLE_PART
