General Searching Instructions -- If you don't know the CAS number for the compound, you may search the CAS number first with chemical name. To search with full chemical name, letters of the chemical name should be entered first. For example, 1,1,2-trichloroethane should be entered as "trichloroethane, 1,1,2-" instead of "1,1,2-trichloroethane". Otherwise, you may just enter "trichloro" to get CAS numbers for all compounds with chemical names containing "trichloro", such as "Trichloroethane, 1,1,1-", "Trichloroethylene", "Trichlorophenol, 2,4,5-", "Fluorotrichloromethane", etc.
