The Telegram API tokens looks like this "123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11" (taken from telegram docs) what you have looks more like a serial number to me, you can register a new bot a see if it's follows the same pattern.
If you want to make your own bot, you can of course, but first you will need to know how the bot communicates with the app so you can send the information.
Hope this helps a little.
