A Laravel package for generate and validating an ISIN (International Securities Identification Number / ISO 6166).

ISINs will be checked against the checksum as detailed at \[[https://en.wikipedia.org/wiki/International\_Securities\_Identification\_Number](https://en.wikipedia.org/wiki/International_Securities_Identification_Number)\]

Installation
------------

[](#installation)

The library can be installed via composer

```
composer require fynduck/isin

```

Usage
-----

[](#usage)

You can instantiate an ISIN object by passing in a string

```
use fynduck\Isin;

$number = 'GB00B3W23161';
$isin = new Isin($number);
```

If the value passed in was not a valid ISIN it will throw a `fynduck\Isin\Exception\InvalidISINException`To get the value back out you can do

```
$isin->getValue();
return GB00B3W23161

```

If you want to get hold of just the check digit you can use

```
$isin->getCheckDigit();
return 1

```

### Generate ISINs

[](#generate-isins)

```
Isin::generateDigit('GB00B3W2316');
return: 1

```

### Validating ISINs

[](#validating-isins)

There are some helper static functions for simple validation.

```
Isin::isValid('GB00B3W23161');
return true

```

This will return true if the value was a valid ISIN, false otherwise.

```
Isin::validate('gb00b3w23161');
return GB00B3W23161

```

```
$number = Isin::validate('ABC');
return InvalidISINException

```

This will return the properly formatted ISIN (whitespace trimmed and converted to uppercase). It will throw a `fynduck\Isin\Exception\InvalidISINException` if the input was not valid.
