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[edit]
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 |
1 | GLGLL |
2 | GLLGL |
3 | GLLLG |
4 | LGGLL |

8 | LGLLG |
9 | LLGLG |

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
