21450-90-8 Usage
General Description
2-Methyl-1-naphthylmagnesium bromide is an organometallic compound that is used as a reagent in organic synthesis. It is a strong nucleophile and is commonly used in Grignard reactions to form carbon-carbon bonds. 2-METHYL-1-NAPHTHYLMAGNESIUM BROMIDE is a derivative of magnesium and bromine, and it is typically prepared by reacting 2-methyl-1-naphthaldehyde with magnesium and bromine. Its reactivity and ability to form new carbon-carbon bonds make it a valuable tool in the field of organic chemistry, enabling the synthesis of a wide range of complex organic molecules.
Check Digit Verification of cas no
The CAS Registry Mumber 21450-90-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,5 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21450-90:
(7*2)+(6*1)+(5*4)+(4*5)+(3*0)+(2*9)+(1*0)=78
78 % 10 = 8
So 21450-90-8 is a valid CAS Registry Number.

Four 1,1'-binaphtyl-2-carboxylic acids were obtained in 38-53 percent isolated yield via three-stage oxidation of 2-methyl-1,1'-binaphtyls, that is, i) NBS-bromination to benzylic bromides, ii) treatment with sodium salt of 2-nitropropane to aldehydes, and iii) KMnO4-oxidation to carboxylic acids.
