Check Digit Verification of cas no
The CAS Registry Mumber 18437-78-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,3 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18437-78:
(7*1)+(6*8)+(5*4)+(4*3)+(3*7)+(2*7)+(1*8)=130
130 % 10 = 0
So 18437-78-0 is a valid CAS Registry Number.

The kinetics of quinuclidine displacement of BH3 from a wide range of Lewis base borane adducts have been measured. Parameterization of these rates has enabled the development of a nucleofugality scale (NFB), shown to quantify and predict the leaving group ability of a range of other Lewis bases. Additivity observed across a number of series R′3-nRnX (X = P, N; R′ = aryl, alkyl) has allowed the formulation of related substituent parameters (nfPB, nfAB), providing a means of calculating NFB values for a range of Lewis bases that extends far beyond those experimentally derived. The utility of the nucleofugality parameter is explored by the correlation of the substituent parameter nfPB with the hydrolyses rates of a series of alkyl and aryl MIDA boronates under neutral conditions. This has allowed the identification of MIDA boronates with heteroatoms proximal to the reacting center, showing unusual kinetic lability or stability to hydrolysis.

Paragraph 0050-0055, (2020/09/09)
The invention discloses an organic long afterglow material with photoactivation characteristic, and a preparation method and application thereof. The chemical structure of the material has a general formula; and R in the formula is H, F, OCH3. According to the invention, the series of compounds are prepared by taking a triphenylphosphine oxide derivative as a research object and connecting different substituents to three benzene ring para-positions of triphenylphosphine oxide. after controlling of the ultraviolet irradiation time, the phosphorescence service life and the intensity of the series of materials are obviously improved. And in combination with different dynamic adjustability, multiple information encryption applications are realized.
