2729-28-4 Usage
General Description
1,1-dichloro-1,2,2,3,3,3-hexafluoropropane, also known as HCFC-225ca, is a colorless, odorless organic compound with the chemical formula C3Cl2F6. It is a halogenated hydrocarbon that is used primarily as a solvent in the electronics industry. HCFC-225ca is a highly stable compound with high ozone depletion potential and global warming potential, leading to its classification as a hazardous substance. Due to its adverse environmental effects, its production and use are being phased out under the Montreal Protocol, an international treaty aimed at protecting the ozone layer. It is important to handle and dispose of 1,1-dichloro-1,2,2,3,3,3-hexafluoropropane with care to minimize its impact on the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 2729-28-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,2 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2729-28:
(6*2)+(5*7)+(4*2)+(3*9)+(2*2)+(1*8)=94
94 % 10 = 4
So 2729-28-4 is a valid CAS Registry Number.

Disclosed is a process comprising reacting CF3CF2CCI2CF2CF3 (CFC-41 -10mca) with hydrogen in the presence of a dehalogenation catalyst to produce CF3CF2CCI=CFCF3 (CFC-1419myx). Also disclosed herein is a process comprising reacting CF3CF2CCI=CFCF3 (CFC- 1419myx) with hydrogen in the presence of a dehalogenation catalyst to produce CF3CF2C≡CCF3 (octafluoro-2-pentyne). Also disclosed herein is a process comprising reacting CF3CF2CCI2CF2CF3 (CFC-41 -10mca) with hydrogen in the presence of a dehalogenation catalyst to produce CF3CF2C≡CCF3 (octafluoro-2-pentyne). In addition, a process for reacting CF3CF2C≡CCF3, in a pressure vessel, with a Lindlar catalyst and hydrogen to produce CF3CF2CH=CHCF3 (1,1,1,4,4,5,5,5-octafluoro-2- pentene) is disclosed.
