Hi, try something like this :
put your identifiers in a list (I call it account) and define a mySelect
function :
account = {... 2, 3, ...}
mySelect[ll_, x_] := Select[ll, #[[1]] == x &]
if
list={{2,3,4,5,77},{2,4,5,66,77},{3,4,7,8,90,6},{3,5,6,7,8,0},{3,45,67,77,12}}
then
mySelect[list, #] & /@ account
should do the job.
