nice try 
but rules are:
1+22+333+4444+55555+666666+7777777+88888888+999999999
without using the numbers themselves.
you must make the numbers and add them.

How do you call this number sequence?

i think your number sequence may be wrong Giz...
f(10) = 1+22+333+4444+55555+666666+7777777+88888888+999999999+10101010101010101010 == 10101010102107494000
#############################################
ungolfed code:
GeSHi`ed javascript code
1
2
3
4
5 | function f(x) { for(s=0,i=x+1;i;s+=+Array(i).join(--i)); return s } |
i might be totally wrong, if so then sorry.
*edit*
yeah i'm totally wrong lol!!!!
sorry guys i was rushing a bit there....

I generated the values with this code:
Edit: I assume it´s a precision problem in your code
GeSHi`ed PHP code
1 2 3 4 56 7 8 9 1011 12 | function f($n) { $fn = "0"; for ($n = $n; $n >= 1; $n = $n - 1) { $rep = str_repeat($n, $n); $fn = bcadd($fn, $rep); } return $fn;} |

written and rewritten from scratch 9 times now to make javascript handle and add as array then print as string for large numbers but each time hit a snag and give up to rewrite and repeat...
therefore my code so far if anybody wants to play about is:
Giz check f(10) http://www.wolframalpha.com/input/?i=1%2B22%2B333%2B4444%2B55555%2B666666%2B7777777%2B88888888%2B999999999%2B10101010101010101010 different result?

If you look, you can see that WolframAlpha interprets 10101010101010101010 as binary. It also provides a link to have it interpreted as decimal, which results in the correct answer.
Besides properly using proper tooling, you can also quite easily see that the last digit has to be 5. (0 for 1+9, 2+8, 3+7, 4+6 and 10, which only leaves 5)

Yeah... reading and calculating with single digits... I should buy a cape. 
And I wouldn't use JS, if I had a choice. But if I would, it would surely not look like the stinking mess you posted. Perhaps you should first try to write proper working code before you go all code golf on it.
For your information: 10*10^0+10*10^1+10*10^2+.. is not ...101010
Also: t.substr(0,1)+t.substr(t.length-1,1) is an interesting way to split a string; I'm sure this will work for all cases.
Oh, one more thing: code golfs sucks balls!

A cape that says "DL" and everyone thinks it stands for 'download'! 
thats not a mess sir, thats half organised broken chaos...
"t.substr(0,1)+t.substr(t.length-1,1)" was broken lol
when i read your posts i have the voice of siri in mind, and you are still yet to explain how you feel about flipping a tortoise onto its back in a desert then not even gving a helping hand, why would you not?
