Shorter checksum than MD5

i'm looking for a simple way to checksum my data.
The data is 70 bytes long per record, so a 32
byte hex md5sum would increase the size of my
mysql db a lot.
I'm looking for something that is 5 bytes long,
for the moment i'm just taking a part of the hex
md5 sum (like this: checksum = md5sum[3:8]). I
don't have any duplicates, and I have over 100000
records, but i'm not sure for the future...
Can anybody give me something better? Or point me
to some website?
PS: I use this checksum to periodically compare 2
versions of this DB, which are on 2 sides of a
slow internet connection. My hope is to keep down
unneeded traffic between the 2 servers.
