9783161484100

9783161484100 is an ISBN-13 commonly used in educational materials to illustrate the structure of International Standard Book Numbers and the method for computing the check digit. When written with hyphens, it appears as 978-3-16-148410-0, a form that highlights the standard segmentation into prefix, group, publisher, item, and check digit.

The 13-digit code begins with the prefix 978, which designates an EAN/UCC-13 barcode. The next group identifier 3 indicates a German-language market. The publisher code 16 and the item number 148410 identify a specific title or edition within that publisher’s catalog, while the final digit 0 is the check digit used to verify the number’s validity. The check digit for 9783161484100 is determined using the ISBN-13 algorithm, which multiplies the digits in odd positions by 1 and even positions by 3, sums the results, and computes a value that brings the total to a multiple of 10. For the first 12 digits (9, 7, 8, 3, 1, 6, 1, 4, 8, 4, 1, 0), the weighted sum equals 100; 100 modulo 10 is 0, and the required check digit is 0, making the full 13-digit number valid.

This exact sequence is widely used as a canonical example in discussions of ISBN-13 structure and error-detection, rather than as a reference to a specific published work. ISBN-13 numbers are now the global standard for book identification and barcoding.
