Algorithem is :

@ByStep_K_004010d8:                          ;<= Procedure Start
        xor eax,014h      ; serial length is 20
        jnz @ByStep_K_00401122 ; if lstrlen(serial)<> 20 Jump to Eax==0
        xor byte ptr ds:[0403059h],041h     ;mov byte ptr ds:[eax+1],41h == 'A' char
        jnz @ByStep_K_00401122 ; if not correct Jump to eax==0
        xor byte ptr ds:[040305ch],054h  ; mov byte ptr ds:[eax+4],54h == 'T' char
        jnz @ByStep_K_00401122    ; if not correct Jump to eax==0
        xor byte ptr ds:[040305fh],02dh  ;mov byte ptr ds:[eax+7],2Dh == '-' char
        jnz @ByStep_K_00401122    ;if not correct Jump to eax==0
