Batch numbers for LDS films

When researching my family in SLC some years back, I copied the film
number (eg. 0218487, pg. 310, 311) for my reference records. I see
now that in order to add this film to our website film list, I must
have a batch number. How do I get a batch number for my film
numbers? I've looked around at the FamilySearch.org site but could
not find a place that tells me batch numbers in relation to the
numbers I have.

I would be happy to add the films to the Neustros files if I could
find the batch numbers.
