That isn't a Public key it is a hash. PubKeys are 256 bits.
{troll mode on}No.
pubkeys are 512 bits.
Yes, it is possible to "compress" it to 257 bits
{troll mode off}
What happens when you put the public key after https://blockchain.info/address/ ?
Nothing because a PubKey is not an address. An address is a hash of the pubkey (PubKeyHash) or a hash of the script (ScriptHash) with version and checksum encoded in base58.

dig into the JavaScript from Bitaddress.org
I'd like to avoid having to make a request to the server to extract the bitcoin address from the public key.
I found another example on how to extract it with PHP (https://stackoverflow.com/questions/19233053/hashing-from-a-public-key-to-a-bitcoin-address-in-php), but I really prefer doing in it Javascript.

I don't know about a javascript implementation, but for python you can check out ours:
https://github.com/orisi/wiki/wiki/Installing-the-oracle-node
And then run ./runclient.sh main
Here's a code that does it:
https://github.com/orisi/orisi/blob/master/src/client/main.py
(function main)

Hello,
I'd like to extract the bitcoin address from a public key.
I want to create a MultiSig address and would like to check if the bitcoin address corresponds to the public key.
Does anyone know if this has already been made with Javascript?
Thanks
