Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. More information about the EC Inventory can be found here. If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. If generated, an InChI string will also be generated and made available for searching. More help available here.
