Here's one way:
SQL> VAR input varchar2(3)
/* Input string */
SQL> EXEC :input := '143'
SQL> SELECT empno,
       ename
  FROM emp,
       (SELECT     SUBSTR (:input, LEVEL, 1) s
              FROM DUAL
        CONNECT BY LEVEL <= LENGTH (:input))
WHERE empno LIKE '%' || s || '%'
/* Exists: */
MPNO ENAME
