40550-18-3 Usage
General Description
Tetrahydro-2,6-dioxo-2H-pyran-3-propionic acid, also known as levulinic acid, is a carboxylic acid with the molecular formula C5H8O3. It is a versatile chemical that can be derived from renewable resources such as biomass and is considered a potential building block for the production of various chemicals and fuels. It has a wide range of applications, including as a solvent, a precursor for plasticizers and polymers, and as a platform chemical for the synthesis of pharmaceuticals and agricultural products. Levulinic acid is also being studied as a potential substitute for petroleum-derived products, making it an important candidate for sustainable and eco-friendly chemical production.
Check Digit Verification of cas no
The CAS Registry Mumber 40550-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,5 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40550-18:
(7*4)+(6*0)+(5*5)+(4*5)+(3*0)+(2*1)+(1*8)=83
83 % 10 = 3
So 40550-18-3 is a valid CAS Registry Number.

Nucleotides: Part LV - Synthesis and Application of a Novel Linker for Solid-Phase Synthesis of Modified Oligonucleotides
Waldvogel, Siegfried R.,Pfleiderer, Wolfgang
, p. 46 - 58 (2007/10/03)
Various bifunctional amino-protecting groups such as the phthaloyl, succinyl, and glutaryl group were investigated as potential linker molecules for attachment to solid-support materials. Pentane-1,3,5-tricarboxylic acid 1,3-anhydride (16) offered the best properties and reacted with the amino groups of differently sugar-protected adenosine (see 20 and 22), cytidine (see 29), and guanosine derivatives (see 32) to the corresponding 2-(2-carhoxyethyl)glutaryl derivatives 23, 24, 30, and 33. The usefulness of the new linker-type molecules was demonstrated by the solid-support synthesis of the potentially antivirally active 3′-deoxyadenylyl-(2′-5′)-2′-adenylic acid 2′-{2-[(adenin-9-yl)methoxy]ethyl} ester (38) starting from the 2′-end with N6,N 6-[2-(2-carboxyethyl)glutaryl]-9-{{2-[(4,4′-dimethoxytrityl) oxy]ethoxy} methyl}adenine (12).
