the Luhn check:

```

package main

import (

    "fmt"

    "github.com/tcort/luhn"

    "os"

)

func main() {

    if len(os.Args) != 2 {

        fmt.Println("Usage: lc [number]")

        return

    }

    if luhn.Check(os.Args[1]) {

        fmt.Println("The number passed the Luhn check")

    } else {

        fmt.Println("The number failed the Luhn check")

    }

}

```
