Phosphorane, difluorotrimethyl-, also known as difluoromethylidynetriphenylphosphorane, is a phosphorus-containing organometallic compound with the chemical formula (CH3)3P=CF2. It is a colorless, volatile, and highly reactive substance that is sensitive to air and moisture. Phosphorane, difluorotrimethyl- is a key intermediate in the synthesis of various organophosphorus compounds, particularly in the preparation of fluorinated organic molecules. Due to its reactivity, it is typically generated in situ and used immediately in reactions to avoid decomposition. Difluorotrimethylphosphorane is known for its ability to act as a Lewis acid and a nucleophile, making it a versatile reagent in organic chemistry.

661-42-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 661-42-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 661-42:
(5*6)+(4*6)+(3*1)+(2*4)+(1*2)=67
67 % 10 = 7
So 661-42-7 is a valid CAS Registry Number.
