CAS numbers are found in the underlying chemical databases (inside USEtox folder, sub-folder "InputData"), sheet "Substance data", column B. These must first be imported into sheet "Substance data" in the USEtox model file before they can be found in the USEtox user interface. If a CAS number is not found, it means that this CAS number is currently not included in USEtox.
