RUT Validation (Chile)

What does the validator check?

Checks if the check digit (0-9 or K) is correct using the modulo 11 algorithm with cyclic weights 2-7 applied right to left.

When is it considered invalid?

When the base number doesn't have 7-8 digits or the calculated check digit doesn't match (including the special case K).

Use in development

Chilean platforms need to validate RUT. The validator helps quickly verify if a RUT is mathematically correct.
