Hello, My Name Is Jolana. I Just Wanted To Find

Hello,
my name is Jolana. I just wanted to find out if DIN number for Novolin 30/70 and Novolin 70/30 is the same.
I think not.
I bought 30/70 today. They gave me receipt for my insurance company with DIN from 30/70 but the name on it is Novolin 70/30.
I'm just wondering if insurance company will accept that.
What do you think?
If nothing, that's fine, too.
Thank you. Have a good night.
Jolana
