1840-42-2 Usage
General Description
Fluorotrinitromethane (CF3NO2) is a pale yellow gas with a pungent odor that is primarily used as a refrigerant. It is also known by the trade name R-813 and is considered a potent greenhouse gas with a high global warming potential. However, it has a very short atmospheric lifetime, which means it does not persist in the atmosphere for long periods of time. The compound is highly reactive and can undergo explosive decomposition under certain conditions, making it potentially hazardous to handle. Due to its environmental impact and potential safety concerns, efforts are being made to find alternative refrigerants that are more sustainable and less harmful to the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 1840-42-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,4 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1840-42:
(6*1)+(5*8)+(4*4)+(3*0)+(2*4)+(1*2)=72
72 % 10 = 2
So 1840-42-2 is a valid CAS Registry Number.

CHEMICAL GENERATION OF TRINITROMETHYL RADICALS IN THE REACTION OF XENON DIFLUORIDE WITH THE NITROFORM ANION
Tselinskii, I. V.,Mel'nikov, A. A.,Trubitsin, A. E.
, p. 619 - 622 (2007/10/02)
In the reaction between the trinitromethane potassium salt and xenon difluoride in acetonitrile in the presence of benzene and THF the trinitromethyl derivatives of benzene and THF are formed in addition to the fluorination products.This indicates that the reaction takes place through the formation of trinitromethyl radicals.
