  <p>Good question.  This is what <a href="https://www.lego.com/en-us/service/help/bricks-building/replacement-parts/identifying-lego-set-and-part-numbers-408100000009668" rel="nofollow noreferrer"><em>LEGO.com</em></a> says about the molded numbers on individual pieces.</p>
  
  <p><a href="https://i.sstatic.net/Vob5D.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/Vob5D.jpg" alt="enter image description here"></a></p>
  
  <p>So, <em>LEGO</em> is saying the molded number is this piece's specific <em>Design Number</em> and that we can plug this number in on their Part Database and find the piece.  </p>
  
  <p>Let's try it...  Hmmm... Seems that answer is flawed.</p>
  
  <p>So, how did I find it?  My initial search for "Duplo 41489", came with the search results below.</p>
  
  <p>We both now know that there is a Star Wars set with this number, who's popularity has, unfortunately, skewed the wanted results for a <em>piece</em>. So, we can ignore anything Star Wars...</p>

Answers.Text: I cross referenced "2949-1 - Remote Control Doze" through Bricklink and it switched this block from "41489c01" to "45751c01".  The Bricklink reference is wrong.  Relinked it to Peeron.com.

Answers.Text: Following the recent update of the answer. Good catch with Peeron! However there's still some inconsistency. Peeron states this piece has been available in [2949](http://www.peeron.com/inv/sets/2949-1) set, however Bricklink has 45751c01 part in its [inventory](https://www.bricklink.com/catalogItemInv.asp?S=2949-1). Who's right then? It is either A). Incorrect inventory on Peeron or Bricklink, or B). This part is missing in BL catalog and needs to be added (and inventory for 2949 set updated, eventually).

The reason behind such statement is simply instructions for [2949](http://bricks.rupprecht.me/?p=2353) set as well as [3589](https://e054fe06-a-62cb3a1a-s-sites.googlegroups.com/site/kensphotopage/vintage/DSCF4970.JPG), where both sets should have same piece in their inventory. However you can clearly see 3589 has quite a few pictures explaining the use for intelligent brick, while 2949 has none. 2949 doesn't seem to have any way connecting intelligent brick to function.

  Good question. This is what [*LEGO.com*](https://www.lego.com/en-us/service/help/bricks-building/replacement-parts/identifying-lego-set-and-part-numbers-408100000009668) says about the molded numbers on individual pieces.
  
  [![enter image description here](https://i.sstatic.net/Vob5D.jpg)](https://i.sstatic.net/Vob5D.jpg)
  
  So, *LEGO* is saying the molded number is this piece's specific *Design Number* and that we can plug this number in on their Part Database and find the piece.
  
  Let's try it... Hmmm... Seems that answer is flawed.
  
  So, how did I find it? My initial search for "Duplo 41489", came with the search results below.
  
  We both now know that there is a Star Wars set with this number, who's popularity has, unfortunately, skewed the wanted results for a *piece*. So, we can ignore anything Star Wars...
  
  ...Look at the third result with no reference to Star Wars.
  
  [![enter image description here](https://i.sstatic.net/y881O.jpg)](https://i.sstatic.net/y881O.jpg)
  
  The third result is pointing to *Peeron*, another LEGO Set Inventory Database, where the molded *Design Number* of this piece is set up correctly.
  
  [![enter image description here](https://i.sstatic.net/Qo4JN.jpg)](https://i.sstatic.net/Qo4JN.jpg)
  
  Let's double check by searching the number through ***[Peeron.com HERE](http://www.peeron.com/)***.
