The National Institute of Standards and Technology (NIST) hosts a variety of different reference datasets freely available to the public. We have picked two databases that could prove useful to you!
A database currently consisting of organic compounds along with a few small inorganic compounds and data on thermochemical, thermophysical, and ion energetics.
Besides the usual search fields, you can search the WebBook for formulas, reactions and structures, as well as making physical property based searches.
Some useful models and tools are also included:
A database aiming to give a comprehensive review of published data for solubilities of gases, liquids and solids in liquids or solids.
The data on solubilities was originally published in the IUPAC and contains over 67,500 solubility measurements, 1800 chemical substances and 5200 chemical systems.

CAS Common Chemistry provides access to several thousand substances and associated data. Now it includes authoritative information on nearly 500,000 substances from CAS REGISTRY. Reusable licensing of content is ensured through a Creative Commons Attribution-NonCommercial (CC BY-NC 4.0) license.
We have full access to the CAS content collection through SciFindern (registration required).
The IUPAC (International Union of Pure and Applied Chemistry) has started a periodic table challenge. It is a new and expanded online challenge. The challenge about the periodic table of the elements 2019 aimed at a global audience of young students during the International Year of the Periodic Table of Chemical Elements (IYPT2019).

The following licenses will not be continued in the new year:
This means from 1 January 2020, the resources will no longer be accessible.
We all or almost all have one, but what elements is a smartphone made of? This periodic table by the European Chemical Society shows around 30 elements and its scarcity. Some 10 million smartphones are being discarded or replaced every month in the European Union and the raw materials are rarely recycled. EuChemS hopes that this thought-provoking periodic table will lead to reflection and ultimately, action.
