Check Digit Verification of cas no

The CAS Registry Mumber 114458-03-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,4,5 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 114458-03:
(8*1)+(7*1)+(6*4)+(5*4)+(4*5)+(3*8)+(2*0)+(1*3)=106
106 % 10 = 6
So 114458-03-6 is a valid CAS Registry Number.

We have analyzed the abundance of bacterial sulfonosphingolipids, including rosette-inducing factors (RIFs), in seven bacterial prey strains by using high-resolution tandem mass spectrometry (HRMS2) and molecular networking (MN) within the Glob

A Unified Approach to Phytosiderophore Natural Products

supporting information, p. 577 - 580 (2020/11/02)

This work reports on the concise total synthesis of eight natural products of the mugineic acid and avenic acid families (phytosiderophores). An innovative ?east-to-west“ assembly of the trimeric products resulted in a high degree of divergence enabling the formation of the final products in just 10 or 11 steps each with a minimum of overall synthetic effort. Chiral pool starting materials (l-malic acid, threonines) were employed for the outer building blocks while the middle building blocks were accessed by diastereo- and enantioselective methods. A highlight of this work consists in the straightforward preparation of epimeric hydroxyazetidine amino acids, useful building blocks on their own, enabling the first synthesis of 3’’-hydroxymugineic acid and 3’’-hydroxy-2’-deoxymugineic acid.

Paragraph 0025; 0038-0040; 0046-0048; 0053-0055; 0060-0062, (2020/05/02)

The invention provides an L-malic acid dimer impurity and a preparation method thereof. The L-malic acid dimer impurity (impurity X) is discovered and separated for the first time, and has a structureshown in the specification. The preparation method of the impurity X comprises the following steps: (1) protecting a carboxyl group at one side of L-malic acid to obtain a compound 1; (2) protectinga carboxyl group at the other side of the compound 1 to obtain a compound 2; (3) hydrolyzing the compound 2 under the condition of acetic acid/water/tetrahydrofuran to obtain a compound 3; (4) dehydrating and condensing the compound 3 to obtain a compound 4; and (5) hydrogenating the compound 4 to remove benzyl groups to obtain the impurity X. The impurity spectrum of malic acid stability researchis expanded, and the improvement of the malic acid quality standard is promoted. The compound property of the L-malic acid dimer impurity is studied, and the L-malic acid dimer impurity has positiveguiding significance for selection of storage conditions of malic acid.
