After today's fltk-dev incident, I decided to do a bulk check, here's the result.
fltk-1.3-dev.tcz corrupt
python3.6-colorama.tcz corrupt
python3.6-evdev.tcz corrupt
simplesceenrecorder-doc.tcz corrupt
simplesceenrecorder.tcz corrupt
#!/bin/bash
base_url="http://distro.ibiblio.org/tinycorelinux/14.x/x86_64/tcz/"
md5_db_url="${base_url}md5.db.gz"
zcat <(wget -qO- "$md5_db_url") | while IFS= read -r line; do
    md5=$(echo "$line" | awk '{print $1}')
    filename=$(echo "$line" | awk '{print $2}')
    remote_file_url="${base_url}${filename}"
    local_md5=$(wget -qO- "$remote_file_url" | md5sum | awk '{print $1}')
    if [ "$md5" != "$local_md5" ]; then
        echo "$filename corrupt"
    fi
done
