How do you want to check if they are registered? By running regedit, from within a Delphi app or some other way?

First of all you have to find out one GUID of each dll. Then you could look if this GUID is found in the registry under
  HKEY_CLASSES_ROOT\CLSID\{---guid---}

Just try to do something that needs those registered files. If they are not properly registered, you will receive a EOleSysError. Write an exceptional handler for this specific exception.
for instance:
try
   HTML1.RequestDoc('http://www.microsoft.com');
except
   on EOleSysError do
   begin
   showmessage('HTML component files not registered properly!');
   end;
end;
