818-99-5 Usage
General Description
1-Fluoro-1,1,3-trichloropropane, also known as FC-221, is a halogenated organic compound with the chemical formula C3H5Cl3F. It is a colorless liquid with a strong and distinct odor. The chemical is primarily used as a solvent for cleaning and degreasing metal and electronics. It is also used in the production of other chemicals and as a refrigerant. However, due to its potential environmental and health hazards, including its classification as a hazardous air pollutant and its potential link to cancer, the use of 1-fluoro-1,1,3-trichloropropane is regulated in many countries. Its production, handling, and disposal are subject to strict regulations to minimize its impact on human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 818-99-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 818-99:
(5*8)+(4*1)+(3*8)+(2*9)+(1*9)=95
95 % 10 = 5
So 818-99-5 is a valid CAS Registry Number.

REACTIONS OF HALOGEN FLUORIDES. X. FLUORINATION OF CHLORINE-SUBSTITUTED ALKANES WITH BROMINE TRIFLUORIDE
Kartashov, A. V.,Chuvatkin, N. N.,Boguslavskaya, L. S.
, p. 2276 - 2278 (2007/10/02)
Bromine trifluoride in Freon 113 readily substitutes the chlorine atoms in monochloroalkanes by fluorine, while in the presence of catalytic amounts of certain Lewis acids it is also capable of substituting the chlorine atoms in polychloroalkanes with the formation of the corresponding fluorides.Additions of tin tetrachloride make it possible not only to increase the reaction rate but also to increase the selectivity of fluorination.In some cases substitution of a primary chlorine atom is accompanied by hydride transfers.
