L-3-Methylaspartic acid, also known as L-3-Methylaspartate, is a naturally occurring amino acid derivative. It is a structural isomer of L-aspartic acid, with a methyl group attached to the third carbon atom of the molecule. L-3-Methylaspartic acid is found in various biological systems and plays a role in certain metabolic processes. L-3-Methylaspartic acid is not an essential amino acid, meaning that it can be synthesized by the human body and does not need to be obtained through diet. It has been studied for its potential neurological effects, as it may influence the activity of certain neurotransmitter systems. The compound is also of interest in the field of chemistry and biochemistry for its unique structure and potential applications in the development of pharmaceuticals and other biologically active compounds.

642-92-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 642-92-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 642-92:
(5*6)+(4*4)+(3*2)+(2*9)+(1*2)=72
72 % 10 = 2
So 642-92-2 is a valid CAS Registry Number.

Indium-mediated allylation and Reformatsky reaction on glyoxylic oximes under ultrasound irradiation

Soengas, Raquel G.,Estévez, Amalia M.

experimental part, p. 916 - 920 (2012/06/04)

A novel and more convenient method for the indium-promoted allylation of glyoxylic oximes based on the use of ultrasonic waves is reported. A similar procedure was used to develop the first example reported in the literature of an indium-mediated Reformatsky reaction on oxime ethers.
