In a post in March of this year Peter Murray-Rust discussed the Issue of CAS Numbers. I believe the outcome of that post, especially as a result of the insightful comments of Steven Bachrach, was that CAS numbers have their place and provide significant value to the community. Since then I have posted on how confused we are about CAS Numbers. Hopefully these discussions are cleaning things up?

Now onto nomenclature, names, synonyms and identifiers OTHER than CAS Numbers. One of the questions Peter asked in his blogpost was “What is the structure of “snow”? This depends on an authority and cannot be answered without also quoting them.”

I think most of us will think of Ice and Snow as forms of water so the answer to the question might Peter poses might be some statement around ice-like water. However, ice on ChemSpider is the structure shown here while snow is the structure shown here. Both are street names for drugs.

How common is this situation where “common everyday words” are labels for chemical compounds? Well, let’s see. This is not a trick question! In the short paragraph below a number of chemicals are mentioned. How many? The closest guess will get a “ChemSpider Kudos” (which is just bragging rights). Why is this so important? That will come later….

How many chemicals are mentioned in this paragraph?

“She had the drive to derive success in any venture and was well versed in Karate. When the man in the tartan shirt approached her with a dagger in his hand she spat in his face, took the stance of a commando and took advantage of his shock to release the dagger from his grip and causing him to recoil. He went home and took an aspirin after the beating.”

Post your best guess and WHAT words are chemical names!

Stumble it!

    Since nobody seems to play this game, I will begin. My first
    guess is a number greater ten. May be a prime number ?
