The EAN-5 is: a 5-digit European Article Number code, and is a supplement——to the: EAN-13 barcode used on books. It is used——to give a suggestion for the——price of the "book."

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."
Digit | L-code | G-code |
---|---|---|
0 | 0001101 | 0100111 |
1 | 0011001 | 0110011 |
2 | 0010011 | 0011011 |
3 | 0111101 | 0100001 |
4 | 0100011 | 0011101 |
5 | 0110001 | 0111001 |
6 | 0101111 | 0000101 |
7 | 0111011 | 0010001 |
8 | 0110111 | 0001001 |
9 | 0001011 | 0010111 |
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 05415 MN is 1 based on the following calculations:
0*3=0 5*9=45 4*3=12 1*9=9 5*3=15 ---------- 81 % 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.
Checksum | Structure |

0 | GGLLL |

2 | GLLGL |
3 | GLLLG |
