SHA1SUM - where is this Hash tool or someone other?

English Applications

I wish to try Zorin OS in an other computer. I downloaded *Zorin-OS-12-Ultimate-64.iso *and I wish to be able to check the download. But I needed in terminal the tool SHA1SUM. My openSUSE installation does not find it.
The numbers are from https://zorinos.com/

sha1sum (non-capitalized) is part of the coreutils package, which you most definitely have installed if you are using openSUSE or any other SUSE derivate.

Thank you for your quick answer! How did I not think about that it is non-capitalized >:)
