2-(1,3-Dithiolan-2-yliden)-5,5-dimethylcyclohexane-1,3-dione, also known as Thioctic acid or Alpha Lipoic Acid (ALA), is a naturally occurring sulfur-containing compound that plays a crucial role in energy production within cells. It is an antioxidant that helps protect cells from oxidative stress and supports the body's ability to convert blood sugar into energy. ALA is found in small amounts in certain foods, such as spinach, broccoli, and yeast, and is also available as a dietary supplement. It is known for its potential benefits in managing diabetes, supporting nerve health, and promoting overall health.

2957-38-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2957-38-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,5 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2957-38:
(6*2)+(5*9)+(4*5)+(3*7)+(2*3)+(1*8)=112
112 % 10 = 2
So 2957-38-2 is a valid CAS Registry Number.

One-Pot Synthesis of 2-Ylidene-1,3-dithiolanes

Lipin,Ershov,Belikov, M. Yu.,Fedossev

, p. 276 - 278 (2019)

A one-pot synthesis of 2-ylidene-1,3-dithiolanes, involving the reaction of carbon disulfide with methylene-active compounds in the presence of sodium ethylate followed by adding 1,2-dichloralkanes to the reaction mixture, is developed.

Synthesis of 2-Ylidene-1,3-dithiolanes

Ershov, O. V.,Lipin, K. V.

, p. 1498 - 1500 (2020/10/02)

Abstract: An environmentally friendly method of synthesis of 2-ylidene-1,3-dithiolanes in the system water–sodium ethene-1,1-dithiolate–haloalkane was developed. The method does not make use of toxic solvents and catalysts and provides high-purity dithiol
