You appear to be using a C-style loop:

if($array[$i] =~ /Check-->\s*\d+$/)
#          ^ C style loop counter?

Sometimes, that's the (only) way to go, but generally, a more idomatic approach is:

for my $array(@array) {
    chomp $array;            # may be unnecessary for your aplication
    if ($array =~ /check-->(\S*\d+)(?:\])$/i) {    # \S Not-a-space, /
+i case insensitive
#                                   ^ also un-needed, for data shown, 
+but a precaution
#                                   against some possible elements in 
+your __DATA__
       my $output = $1;     # Good approach; avoids reusing a left-ove
+r match
