The EAN-5 is a supplement to the EAN-13 barcode used on books. It is used to give a suggestion for the price of the book. ISBN Encoding – Country and Currency Values Description ==Encoding== The Encoding of EAN-5 characters is very similar to that of the other European Article Numbers. The only difference is that the digits are separated by 01. The EAN-5 always begins with '01011.' Also, the R-Code is not used. The structure of the barcode is based on the checksum. In order to compute the checksum, multiply each of the digits by either 3 or 9, alternating each time. Then add them and then do a mod 10. So the checksum for 52495 is 1 based on the following calculations: 5 *3=15 2 *9=18 4 *3=12 9 *9=81 5 *3=15 ---------- 141 % 10 = 1 Once you have the checksum digit, you can look up the structure in the following table. Note that the checksum digit is not in the final 5 digits, and is not intended to validate the 5 digit data, but rather to validate the reading of the EAN-5 overall. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「EAN 5」の詳細全文を読む スポンサード リンク
