Since the experts have not answered you yet, us novices rise up...
Here's two fragments to look at.
cols := #('1' '2' 34 $5 '67' '8').
strm := WriteStream on: ''.
cols do: [ :o | strm nextPutAll: o asString ].
strm contents asNumber. "inspect --> 12345678"
"then do...."
strm reset.
cols do: [ :o | strm nextPut: o asString first].
strm contents asNumber. "inspect --> 123568"
Though your example had strings as the collection's elements, Character
is probably the best choice (like $5 above). Otherwise you have to deal
with each element's possibly having multiple characters each, and either
accomodate them (fragment 1) or ignore the additional ones (fragment 2).
I hope this helps you explore towards your "final answer"!
Cheers,
John
P.S. New Emoticons/Smileys(/Smallies?), what do y'all think:

[:o| self enhance: o] -- Buster wearing T-Shirt expressing:
"I add value to everything I'm given"
