Pentamethylphosphorane, also known as (MeO)5P, is a highly reactive organophosphorus compound with the chemical formula (CH3O)5P. It is a colorless, volatile, and pyrophoric liquid, which means it can ignite spontaneously upon contact with air. Pentamethylphosphorane is a strong Lewis acid and a powerful methylating agent, commonly used in organic synthesis to transfer a methyl group to various substrates, such as alcohols, amines, and carboxylic acids. Due to its high reactivity, it is typically generated in situ and handled under an inert atmosphere to prevent unwanted side reactions. The compound plays a significant role in various chemical transformations, such as the formation of ethers, esters, and other organic compounds, making it an important reagent in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 1455-07-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1455-07:
(6*1)+(5*4)+(4*5)+(3*5)+(2*0)+(1*7)=68
68 % 10 = 8
So 1455-07-8 is a valid CAS Registry Number.
