[Koha] MARC Communications Format Records

Pasted below and also in an attachment to this message are 3 bibliographic records in MARC communications format. We have about 100,000 more just like these 3 that we would like to load into Koha. If you look closely, you will also see a "database control number" in the form of 3 letters followed by a dash and 4 digits right after the stream of numbers at the beginning of each record. It looks like we will have to convert this alphanumeric value into an integer in order to use it as the biblionumber in Koha. Can anyone suggest how we might load these records and convert the database control number?
