Content Type ID's

You are right - we all know how Content Type Id's are constructred. But let me post it here again:

The first part of a CT ID is based on a hexadecimal number that identifies its base content type (see list below) followed by 00 as a seperator. The last part of a CT ID is a GUID that uniquely identifies the CT. For each level o inheritance the seperator will be added to the end of the ID plus another GUID.

So, that's easy and actually not the reason why I wrote this entry. Main reason is, that I always have to look up the base intheritance ID's. So the list below will be my point of contact to get the right ID's easily. Maybe you can use it too:
