"Result: 1234561 barcode"

That is probably wrong. My implementation from the description and two other sources gives 1234565.

Also, the next example is 1234561 encoded with a check digit, that when read is 12345618 which is what my code and the other two sources also results in.

The 1234561 is correct if starting with weight 1 instead of the correct 3.

Hello, and thank you for your contributions to Wikipedia. I noticed that you recently added commentary to an article, Industrial 2 of 5. While Wikipedia welcomes editors' opinions on an article and how it could be changed, these comments are more appropriate for the article's accompanying talk page. If you post your comments there, other editors working on the same article will notice and respond to them, and your comments will not disrupt the flow of the article. However, keep in mind that even on the talk page of an article, you should limit your discussion to improving the article. Article talk pages are not the place to discuss opinions of the subject of articles, nor are such pages a forum. Thank you. GorillaWarfare (she/her • talk) 20:08, 21 October 2023 (UTC)
