REGEX all invoice item descriptions - regex

Question

I'm trying to regex all items from an invoice (name, unit price, total, VAT, etc.). Managed to get all the information regarding digits, but biggest problem si to extract the item descriptions as sometimes it's on two separate lines. This is what I need to regex

22 Tus pentru stampila Pelikan, cu picurator, 28 ml, negru buc. 1.00 6,93 6,93 1,32

Notice that the item description sometimes is after the total price. Problem is that the space between items isn't even, it's variable, like for e.g. position 8 and 9 are almost linked, compared to position 20 and 21 which have a lot of space between them.
Somebody helped me and got only the first line using
\d{1,2}(.*)(\d+\.\d+\s+)(\d+\,\d+\s{0,1}){3}
this is where I got stuck because of the uneven syntax.
It only gets the first line. For e.g.:
'''
16 Notite adezive OFFICE Products, 51 x 76 mm, galben pal, buc. 5.00 1,65 8,25 1,57
100 file (14047511-06)
'''
it gest only 16 Notite adezive OFFICE Products, 51 x 76 mm, galben pal, buc. 5.00 1,65 8,25 1,57 but not 100 file (14047511-06). The complete invoice description is Notite adezive OFFICE Products, 51 x 76 mm, galben pal, 100 file (14047511-06) when transformed from pdf to text this is how I get the files.
Will need to extract also the last part and merge the first one to get the full item description.
Thank you

Try this regex:
\d{1,2}(.*)(\d+\.\d+\s+)(\d+\,\d+\s?){3}([\n ]+[^(\n]*\([^)]+\)(?=\n))?
