Hello everyone, I need your help, I have a file like this:

>1

AACTCTGGGACAATGGCACACGGGAAACAGATAATGAACGATCAGCACAGGGAACTAGCG

And I would like to change all the numbers by a list of words, I made the next program with perl but I am new using the program and I dont know who is wrong with that.

%lista2=(
1    =>    "CAT00.3",
2    =>    "CAT43.1",
3    =>    "CAT40.3"
);

open(OA,">file2.txt");

foreach $key (keys %lista2){
open(SAL,"file.txt");
while(<SAL>) {
        chomp;
            if(/>/) {
            @w=split("\t");            
                $r=0;
                s/\;//g;
                if (/%lista2[i]/) {                
                    print OA "$_ $lista2{$key}\n" ;
                    $r=1;
                    }
                }
            }
            
        }
close(SAL);
close(OA);
