Use a test like this:
if not values.get('number'):

In Tryton required means not False for Python so it includes None,
empty string, empty list, empty dictionary etc.

The constraint on removing "NOT NULL" only by the original module is
there on purpose because once a field is required all depending code
will not manage the case if it is empty. So we must ensure that there
will be always a value.
Also it is the reason why we must be careful when setting a field
required.
