How to find serial number

[Candice28]

I have an old version of Photoshop CS6 Extended--Student/Teacher edition.  I purchased it years ago when I worked at an educational institution.  I still have the box with the Product Number adn disc, but don't have my Serial Number.  I got a new Macbook Pro and want to install it on my new computer.  It is currently still installed on my old Macbook, but I will deactivate that, once I know I can reactivate it.  

How do I get my serial number????

CS6 will not work with MAC Catalina

Blah. I was afraid of that.  Super annoying that I have to purchase photoshop again when I have a version that works fine for my needs
