Can OpenEMPI perform the function of generating a new ID for a person?

Hi all,

In the NHS (UK), they issue an NHS ID to every person who first visits a
general practice (GP). People go to their GP, present proof of identify
(eg, passport) and the GP is able to generate a unique number for them.

I know OPenEMPI can generate uids for persons but can the syntax of these
uids be configured to be: 9 digits +1 check digit?
