According to http://sima-pc.com/nif.php
Your example should not exist.
Have you the rules to validate this number?

By the way, on wikipedia I saw there is a new format "100 nnnn nn" with modulo 
9755.
Do you have any examples?

Sorry, no more examples.

My example above is a valid VAT number for an existing Organisation in the UK.
Please test at this site if you are unsure. It is the official vat validation 
site: http://ec.europa.eu/taxation_customs/vies/

If sima-pc.com does not have that case, then it is not updated.
You can find some good details on the uk validation here:
