ABN
===

This package validates Australian Business Numbers (ABNs) and converts Australian Company Numbers (ACNs) or Australian Registered Body Numbers (ARBNs) to ABNs.

The following example show checking of a valid and an invalid ABN::

    >>> import abn
    >>> abn.validate('53004085616')
    '53 004 085 616'

    >>> abn.validate('99999999999')
    False


To calculate the ABN based on an existing ACN or ARBN::

    >>> abn.acn_to_abn('004085616')
    '53 004 085 616'


To run the tests::

    $ python tests.py
