Hola, buena explicación sobre el RUT y el módulo 11.
También si usan elixir está disponible esta lib github.com/elixirCL/rut
This post gives a clear and practical breakdown of how the Chilean RUT works, especially the Modulo 11 algorithm, which Wikipedia also describes as a widely used checksum method for preventing identification errors. The explanation about combining digit-verification with regex patterns shows why relying solely on the verifier isn’t enough for real-world validation. Tools that follow this structure, like the Chilean RUT lookup system, also depend on these verified rules to ensure accuracy and reliability.
Hola! Muy bien explicado!
Para Python existe esta librería github.com/cve-zh00/PyRut
