The Verhoeff algorithm is an error detection method used primarily for validating identifiers, such as in various forms of numerical codes (e.g., ISBNs, credit card numbers, etc.). It is particularly good at catching single-digit errors, adjacent transpositions, or even some types of multiple errors. ### Key Features of the Verhoeff Algorithm: 1. **Base**: The algorithm operates in base 10, which means it uses the digits 0-9.
