Oct 20 2010 4:44PM	Normal	Fixed	An error later corrected in DSSTox files incorrectly mapped CAS 25013-16-5 to L(-)-Nicotine (ChemSpider ID 80863). You list this as the preferred structure probably due to our assignment. This CAS should be mapped to "butylated hydroxy anisole (unspecified). Chemspider ID 8145 is a particular form that lists BHA as well. Thank you for the comment, the CAS number whici you have highlighted has been removed.
