yep, that does match last field - however I get no difference with just
'?i:'; also, simple

  /":*:e:".+?"([[:print:]]+?)".*?\n/

seems to do the job as well, for last non-null-value-in-quotes, whereas
 
  /":*:e:".+?"([[:print:]]+?)".*\n/

would yield the 1st such value after :*:e:.

unfortunatly CSV isn't that simple to parse - here's eg saved from OOo:

"8,7",0,65,99,"7,22","196,7",01.29,"8,2","NO","0,28","0,12"
"9,8",0,40,76,"8,28","527,9",08.53,"14,2","NNO","0,32","0,14"
"8,4",0,40,61,"7,95","465,4",09.16,"13,9","NNO","0,31","0,14"
"5,8",0,51,91,"6,71","261,3",01.30,"10,5","NO","0,26","0,12"
"5,8",0,51,91,"6"",""709","261,3",01.30,"10,5","NO",,

note unquoted fields and last line, 5th field's value is '6","709'
