As users of ChemSpider will know we went live in late March in a beta state. We have received a lot of constructive feedback and for that we thank you! Some of the feedback has come via circuitous routes and we have responded. We commented that we had worked on the multicomponent mass issue and were trying to find enough time and horsepower to recalculate and publish >10 million compound values again. Time and horsepower is an issue!
The work is underway as evidenced by the new values for Calcium Carbonate identified previously as incorrect and as shown below.
As of this posting about 2.1 million of the 10.6 million records are recalculated and posted and we expect to finish in the next 72 hours.Stumble it!
