    * 6: This is the check digit, I won't go into the detail of how it is calculated but just know that its value depends on the 12 previous digits.
+One last thing to mention is that you might runs into EAN barcodes that ends with a ">" (greater than) symbol (see the image above). This is called a guard mark and it is not part of the barcode per se, it is just used to help barcode readers read it properly. I have also heard that some barcodes can start with "<" (lesser than) this also works in the same way and is not considered part of the barcode so you can safely omit them when cataloging.
