Check Digit Verification of cas no

The CAS Registry Mumber 459200-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,9,2,0 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 459200-98:
(8*4)+(7*5)+(6*9)+(5*2)+(4*0)+(3*0)+(2*9)+(1*8)=157
157 % 10 = 7
So 459200-98-7 is a valid CAS Registry Number.

A copper-templated, bifunctional organocatalyst: A strongly cooperative dynamic system for the aldol reaction

Serra-Pont, Anna,Alfonso, Ignacio,Solà, Jordi,Jimeno, Ciril

, p. 6584 - 6591 (2017)

The study of novel metal-templated dynamic organocatalytic systems has led to the identification of CuSO4 as the most efficient template to assemble monofunctional prolinamide- and thiourea-modified pyridine ligands. The structural and electron

Hydrogen-Bond Catalysis of Imine Exchange in Dynamic Covalent Systems

Schaufelberger, Fredrik,Seigel, Karolina,Ramstr?m, Olof

supporting information, p. 15581 - 15588 (2020/10/02)

The reversibility of imine bonds has been exploited to great effect in the field of dynamic covalent chemistry, with applications such as preparation of functional systems, dynamic materials, molecular machines, and covalent organic frameworks. However, acid catalysis is commonly needed for efficient equilibration of imine mixtures. Herein, it is demonstrated that hydrogen bond donors such as thioureas and squaramides can catalyze the equilibration of dynamic imine systems under unprecedentedly mild conditions. Catalysis occurs in a range of solvents and in the presence of many sensitive additives, showing moderate to good rate accelerations for both imine metathesis and transimination with amines, hydrazines, and hydroxylamines. Furthermore, the catalyst proved simple to immobilize, introducing both reusability and extended control of the equilibration process.

METHODS OF PRODUCING METAL SUFLIDES, METAL SELENIDES, AND METAL SULFIDES/SELENIDES HAVING CONTROLLED ARCHITECTURES USING KINETIC CONTROL

Paragraph 0204; 0205; 0206, (2017/05/28)

The present invention is directed to methods of preparing metal sulfide, metal selenide, or metal sulfide/selenide nanoparticles and the products derived therefrom. In various embodiments, the nanoparticles are derived from the reaction between precursor metal salts and certain sulfur- and/or selenium-containing precursors each independently having a structure of Formula (I), (II), or (III), or an isomer, salt, or tautomer thereof, where Q1,Q2,Q3,R1,R2,R3,R5, and X are defined within the specification.
