4-Chlorophenylmagnesium bromide is an organomagnesium compound with the chemical formula C6H4ClMgBr. It is a colorless to pale yellow liquid that is highly reactive and sensitive to air and moisture. 4-chlorophenylmagnesium bromide is an important intermediate in organic synthesis, particularly in the preparation of various pharmaceuticals, agrochemicals, and other specialty chemicals. It is generated by the reaction of 4-chlorobromobenzene with magnesium metal, and it serves as a nucleophile in various organic reactions, such as Grignard reactions, where it can add to carbonyl groups to form alcohols. Due to its reactivity, 4-chlorophenylmagnesium bromide must be handled under an inert atmosphere, typically using Schlenk techniques or in a glovebox, to prevent unwanted side reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 73-77-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73-77:
(4*7)+(3*3)+(2*7)+(1*7)=58
58 % 10 = 8
So 73-77-8 is a valid CAS Registry Number.
