Ideally, you would make a note of the hash value that you store alongside the ISO file from where you downloaded it (presumably Microsoft). That way you can always remind yourself what the correct value is, then compute the corresponding hash value (MD5, SHA1 or SHA256) of the file anew and compare it to the original hash value that you have on record. This way you don't have to worry if Microsoft or any other party you download your files from kills the service that provided this bit of inforamtion, or if the company itself goes out of business.
As it has been noted, Microsoft has decided to remove this information from public view when they revised their MSDN program. However, if you are willing to trust a third party provider, the same information is readily available at Heidoc.net. It is much better than the yooneed.one site you linked to in that it not only provides you with hash values for a handful of Windows 10 images, but the hash values for the entire MSDN catalog. At the time of this writing, the metadata for 67253 files is browseable and searchable (by SHA1 or SHA256 hash values or by text, i.e. title).
For posterity, here's a screenshot of what the interface looks like.
And here you will find the metadata for the file you used in your example, along with a short description of what it is.
Windows 10 Enterprise 2016 LTSB N (x64) - DVD (English-United Kingdom)
This is the best such database I have found. I'm not sure there is any other, it's the only one I know of, and frankly it is better than what Microsoft provides. I have used it a few dozen times over the past 3 years or so and it has always proven to be accurate. Also, there are no ads, the interface is very clean and easy to use.
