Check Digit Verification of cas no

The CAS Registry Mumber 73991-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,9 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73991-95:
(7*7)+(6*3)+(5*9)+(4*9)+(3*1)+(2*9)+(1*5)=174
174 % 10 = 4
So 73991-95-4 is a valid CAS Registry Number.

supporting information, (2022/01/04)

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

Preparation method of alpha-hydroxyl-gamma-butyrolactone

-

Paragraph 0020; 0021, (2021/06/13)

The invention belongs to the field of preparation of organic compounds, and provides a preparation method of alpha-hydroxyl-gamma-butyrolactone. The method is characterized in that malic acid is used as a raw material, and alpha-hydroxyl-gamma-butyrolactone is synthesized with high yield through four steps of reactions, namely, carboxyl and alpha-hydroxyl protection, beta-carboxyl reduction, protecting group removal and internal esterification. The method has the advantages of easily available raw materials, mild reaction conditions and low cost, and is suitable for large-scale preparation of alpha-hydroxy-gamma-butyrolactone.

L-malic acid dimer impurity and preparation method thereof

-

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.
