Hyphen or not?
editThe reference has "tetra-tert-butyl-ethylene", but should it be "tetra-tert-butylethylene"? --Jorge Stolfi (talk) 20:28, 18 November 2009 (UTC)
- Naming compounds like this without the extra hyphen, "tetra-tert-butylethylene", is more common. But it's not wrong either way. -- Ed (Edgar181) 16:41, 20 November 2009 (UTC)
Chembox misleading: no CAS number?
editThe chembox is misleading because after all this is a hypothetical molecule, also the CAS number link leads to a sorry-not-found page. I do not think CAS hands out numbers for as-yet non existing molecules V8rik (talk) 20:34, 21 November 2009 (UTC)
- Chemical Abstracts does indeed give numbers to compounds that have not been made. The one in the chembox for this article is correct. Chemical Abstracts gives a CAS number to every compound that is mentioned in the chemical literature including those that are studied only theoretically. The "Common Chemistry" site that the CAS number links to in the chembox only lists a small subset of most common chemicals, so in most cases links to that page give the "No CAS Registry Number matched your search" result. -- Ed (Edgar181) 22:08, 24 November 2009 (UTC)
