1-Nitro-heptafluor(n)propan, also known as 1-nitro-1,1,2,2,3,3,4-heptafluoropropane or C3F7NO2, is a colorless, volatile liquid with a molecular formula of C3HF7NO2 and a molecular weight of 181.02 g/mol. It is a derivative of propane with one hydrogen atom replaced by a nitro group and the remaining hydrogen atoms replaced by fluorine atoms. This chemical compound is primarily used as a refrigerant, blowing agent, and fire suppressant due to its low toxicity, non-flammability, and high chemical stability. It is also employed in the production of other fluorochemicals and as a solvent in various industrial applications. However, due to its potential environmental impact, its use is being phased out in some regions, and alternative compounds are being developed.
The CAS Registry Mumber 423-33-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 3 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 423-33: (5*4)+(4*2)+(3*3)+(2*3)+(1*3)=46 46 % 10 = 6 So 423-33-6 is a valid CAS Registry Number.
