Boron trifluoride tetrahydrofuran complex (BF3·THF) is a chemical compound consisting of boron trifluoride (BF3) and tetrahydrofuran (THF) molecules. It is a colorless, volatile liquid that is widely used as a Lewis acid catalyst in various organic reactions, such as Friedel-Crafts acylation and alkylation, esterification, and polymerization processes. The complex is formed by the coordination of THF molecules to the boron atom in BF3, which enhances the solubility and stability of the compound. BF3·THF is known for its high reactivity and selectivity, making it a valuable tool in the synthesis of various organic compounds. However, it is also highly toxic and corrosive, requiring careful handling and proper safety measures during its use.

Check Digit Verification of cas no

The CAS Registry Mumber 407-77-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 407-77:
(5*4)+(4*0)+(3*7)+(2*7)+(1*7)=62
62 % 10 = 2
So 407-77-2 is a valid CAS Registry Number.
