Using rowid in where clause?

Is there a way I can write the query below? This is on 11203

SYSTEM @ bsbc1_db06 > select segment_name,bytes, block_id, file_id

  2  from dba_extents

  3  where dbms_rowid.rowid_block_number(rowid)=1020387

  4  and dbms_rowid.rowid_relative_fno(rowid)=8;

where dbms_rowid.rowid_block_number(rowid)=1020387

                                    *

ERROR at line 3:

ORA-01446: cannot select ROWID from, or sample, a view with DISTINCT, GROUP BY, etc.

I'm trying to find the segment name and the bytes against dbms_rowid.rowid_relative_fno(rowid)=8 and dbms_rowid.rowid_block_number(rowid)=1020387

Thanks
