420-03-1 Usage
General Description
Fluoromethanol, also known as methyl fluoride, is a chemical compound with the formula CH3F. It is a colorless, flammable gas with a faint ether-like odor. Fluoromethanol is primarily used as a solvent in the production of agricultural chemicals, pharmaceuticals, and other chemical manufacturing processes. It is also used as a refrigerant and as a propellant in aerosol products. However, fluoromethanol is toxic and its inhalation or ingestion can cause harmful effects on the body, including respiratory and nervous system disorders. Due to its hazardous properties, fluoromethanol should be handled and used with caution and in accordance with safety guidelines and regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 420-03-1 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 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 420-03:
(5*4)+(4*2)+(3*0)+(2*0)+(1*3)=31
31 % 10 = 1
So 420-03-1 is a valid CAS Registry Number.

Pathways of the reactions of nucleophilic addition of H2O and HF molecules to formaldehyde in the gas phase and in the complex with formic acid: ab initio calculations
Minyaev,Starikov,Lepin
, p. 2078 - 2086 (1998)
The gradient pathways of the reactions of nucleophilic addition of H2O and HF molecules to formaldehyde in the gas phase and in the XH...H2CO...HC(O)OH complex (X = OH, F) were calculated by the ab initio RHF/6-31G**, MP2(fc)/6-31G**, and MP2(full)/6-311++G** methods. Both reactions proceed concertedly. The formation of H-bonded bimolecular pre-reaction complexes is the initial stage of the gas-phase reactions; at the same time, no indications of the formation of stable π-complexes were found on the potential energy surfaces of systems under study. The calculated energy barriers to the gas-phase reactions exceed 40 kcal mol-1, while those to reactions in the complex XH...H2CO...HC(O)OH (X = OH, F) become more than halved.
