digitorus / iso7064

Package iso7064 is a GO implementation of ISO 7064 used in validation of format like IBAN, ISTC, ISNI, LEI, etc.

Golang ISO 7064 validator

This package providers a validtor for the ISO 7064 format like IBAN, ISTC, ISNI, LEI, etc. Currently this package is hardcoded to validate against MOD 97-10 using numeric strings with two check digits. Please feel free to contribute other ISO 7064 algorithms such as MOD 11-2, 37-2, 661-26 etc.

The initial version of this package is based the IBAN validator from https://github.com/almerlucke/go-iban

Contributions

We are looking for contribution to add the following functionality:

• Calculate a new checksum value
• Exctract the checksum value of a given value
• Support other modes ISO 7064 algorithms such as MOD 11-2, 37-2, 661-26 etc.
• Provider helpers (rearrangers) for specific implementations like IBAN
• Add more implementation tests

Example

package main

import (
	"fmt"
	"github.com/digitorus/iso7064"
)

func main() {
	if !iso7064.IsValid("9845000Q555DEB9E2A69") {
		fmt.Printf("%v\n", err)
		return
	}

    	fmt.Println("Valid ISO 7064 value")
}
