Check Digit Verification of cas no

The CAS Registry Mumber 5796-17-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,9 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5796-17:
(6*5)+(5*7)+(4*9)+(3*6)+(2*1)+(1*7)=128
128 % 10 = 8
So 5796-17-8 is a valid CAS Registry Number.

Highly Stable Zr(IV)-Based Metal-Organic Frameworks for Chiral Separation in Reversed-Phase Liquid Chromatography

Jiang, Hong,Yang, Kuiwei,Zhao, Xiangxiang,Zhang, Wenqiang,Liu, Yan,Jiang, Jianwen,Cui, Yong

supporting information, p. 390 - 398 (2021/01/13)

Separation of racemic mixtures is of great importance and interest in chemistry and pharmacology. Porous materials including metal-organic frameworks (MOFs) have been widely explored as chiral stationary phases (CSPs) in chiral resolution. However, it remains a challenge to develop new CSPs for reversed-phase high-performance liquid chromatography (RP-HPLC), which is the most popular chromatographic mode and accounts for over 90% of all separations. Here we demonstrated for the first time that highly stable Zr-based MOFs can be efficient CSPs for RP-HPLC. By elaborately designing and synthesizing three tetracarboxylate ligands of enantiopure 1,1′-biphenyl-20-crown-6, we prepared three chiral porous Zr(IV)-MOFs with the framework formula [Zr6O4(OH)8(H2O)4(L)2]. They share the same flu topological structure but channels of different sizes and display excellent tolerance to water, acid, and base. Chiral crown ether moieties are periodically aligned within the framework channels, allowing for stereoselective recognition of guest molecules via supramolecular interactions. Under acidic aqueous eluent conditions, the Zr-MOF-packed HPLC columns provide high resolution, selectivity, and durability for the separation of a variety of model racemates, including unprotected and protected amino acids and N-containing drugs, which are comparable to or even superior to several commercial chiral columns for HPLC separation. DFT calculations suggest that the Zr-MOF provides a confined microenvironment for chiral crown ethers that dictates the separation selectivity.

The preparation method of the levodopa intermediate derivatives

-

, (2017/10/13)

The invention relates to a preparation method for a levodopa intermediate derivative. The preparation method comprises: in a solvent, reacting 3, 4-dimethoxybenzene phenylalanine shown as formula I with (+)-tartaric acid derivative to obtain the salt of a [(-)-3, 4-dimethoxybenzene phenylalanine]2.(+)- tartaric acid derivative. The solvent includes an alcohol solvent and an ester solvent. The racemization method includes: in the solvent, under the action of an aldehyde or ketone catalyst, reacting the 3, 4-dimethoxybenzene phenylalanine shown as formula I at 0-90DEG C for 0.5-24 h. The preparation method for the levodopa intermediate derivative provided by the invention has simple steps, and the prepared enantiomer has high purity and is low in cost, thus being applicable to industrial production.
