99-68-3 Usage
General Description
Carboxymethylmercaptosuccinic acid, also known as mercaptosuccinic acid or mercaptoundecanoic acid, is a water-soluble organic compound that contains a carboxylic acid group and a thiol group. It is widely used as a chelating agent in various industrial and pharmaceutical applications, particularly in the production of food additives, cosmetics, and pharmaceuticals. The compound is known for its ability to bind to metal ions, such as calcium, magnesium, and zinc, and form stable complexes, making it a popular ingredient in metal sequestration and metal chelation processes. Additionally, carboxymethylmercaptosuccinic acid has been studied for its potential role in environmental remediation and as a corrosion inhibitor in metalworking fluids.
Check Digit Verification of cas no
The CAS Registry Mumber 99-68-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99-68:
(4*9)+(3*9)+(2*6)+(1*8)=83
83 % 10 = 3
So 99-68-3 is a valid CAS Registry Number.

Reductive coupling of aldehydes by H2S in aqueous solutions, a C-C bond forming reaction of prebiotic interest
Kajjout, Mohammed,Hebting, Yanek,Albrecht, Pierre,Adam, Pierre
experimental part, p. 714 - 726 (2012/07/14)
We report here a novel reductive coupling reaction of conjugated, non- or poorly enolizable aldehydes induced by H2S and operative in aqueous solutions under prebiotically relevant conditions. This reaction leads from retinal to β-carotene, and from benzylic aldehydes to the corresponding diarylethylenes. This novel reaction also opens a new potentially prebiotic pathway leading from glyoxylic acid to various compounds that are involved in the reductive tricarboxylic acid cycle. This C-C bond forming reaction of prebiotic interest might have been operative, notably, in the sulfide-rich environments of hydrothermal vents, which have been postulated as possible sites for the first steps of organic chemical evolution.
