way to a column be filled automatically by what is written on others

Is there any way to a column be filled automatically by what is written on others columns.

Example: If one of the cells A2 or B2 and C2 are Nonblank, fills automatically the cell H2 with "ABC2" And If some of the cells D2 and E2 are Nonblank fills the cell H2 with "DE2"

Thanks

something like:

=if(Or(A2<>"",B2<>"",C2<>""),"ABCD2",IF(Or(D2<>"",E2<>""),"DE2","")
