Trimethylaminetrifluoroborane, also known as (CH3)3N·BF3, is a colorless, volatile, and hygroscopic liquid that is widely used as a Lewis acid catalyst in various organic reactions. It is formed by the reaction of trimethylamine (CH3)3N and boron trifluoride (BF3). trimethylaminetrifluoroborane is highly reactive and can act as a strong Lewis acid, facilitating the formation of carbocations and promoting various chemical transformations, such as Friedel-Crafts reactions, alkylation, and polymerization processes. Due to its sensitivity to moisture and air, it is typically stored under an inert atmosphere and handled with care. Trimethylaminetrifluoroborane is also known for its ability to form stable adducts with various substrates, which can be useful in controlling reaction selectivity and improving yields in synthetic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 420-20-2 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, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 420-20:
(5*4)+(4*2)+(3*0)+(2*2)+(1*0)=32
32 % 10 = 2
So 420-20-2 is a valid CAS Registry Number.
