ISODecimal format is 15 digit number. however, some formats use special characters to separate the manufacturer code (first 3) and the aniumal id (last 12), characters such as period (.), underscore (_), and forward-slash (/), as well as potentially more periods separating the animal ID into chunks of 3 (e.g., see ICAR registry). The detection code should handle this.
