# 12 : Identify a Stellar Classic Asset using stellar-sdk.

How can we know if a specific asset is a Stellar Classic Asset?

Create an asset:

```
bash quickstart.sh standalone
bash run.sh
node src/friendbot.js
node src/issueAsset.js AAA
```

This will return:

```
ASSET ISSUED:  Asset {
  code: 'ABCD',
  issuer: 'GAM5XOXRUWPMKENBGOEAKMLRQ4ENHLHDSU2L2J7TVJ34ZI7S6PHMYIGI'
}
```

## From a SYMBOL:ISSUER address

1.- See if the combination have a correct format:

```javascript
var asset = new StellarSdk.Asset(asset_code, asset_issuer );
```

This will create an asset object. If either the asset\_code or the asset\_issuer are not in a good format, this will fail.

Test with:

```
node src/chapter12/checkFormat.js ABC GAM5XOXRUWPMKENBGOEAKMLRQ4ENHLHDSU2L2J7TVJ34ZI7S6PHMYIGI
```

## See if the asset exist?

Can we know if for an asset we have totalSupply or something?

Can we use this in stellar-sdk?

```
