133339-10-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133339-10-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,3 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133339-10:
(8*1)+(7*3)+(6*3)+(5*3)+(4*3)+(3*9)+(2*1)+(1*0)=103
103 % 10 = 3
So 133339-10-3 is a valid CAS Registry Number.

Evidence for a catalytic six-membered cyclic transition state in aminolysis of 4-nitrophenyl 3,5-dinitrobenzoate in acetonitrile: Comparative Br?nsted-type plot, entropy of activation, and deuterium kinetic isotope effects

Um, Ik-Hwan,Kim, Min-Young,Bae, Ae-Ri,Dust, Julian M.,Buncel, Erwin

, p. 217 - 222 (2015)

A kinetic study for reactions of 4-nitrophenyl 3,5-dinitrobenzoate (1a) with a series of cyclic secondary amines in acetonitrile is reported. Plots of the pseudo-firstorder rate constant (kobsd) vs [amine] curve upward, while those of kobs

Paragraph 0435; 0436; 0437; 0438, (2016/10/08)

The invention discloses 2-aminopyrimidine compounds as well as pharmaceutical compositions and applications thereof. The structure of the 2-aminopyrimidine compounds is shown in the formula I, definitions of R1, R2, R3, R4, R5, X, Y, Z and W in the formula are shown in the specification and the claim. The compounds can effectively inhibit growths of a plurality of tumor cells, generate inhibition effects for EGFR and IGF1R protease, and is used for preparing antitumor drugs; the compounds can overcome drug resistance which is induced by prior medicaments Gefitinib and Erlotinib and the like, has selectivity for tumor, especially wild type non-small cell lung cancers, and has good pharmacokinetics property.
