28917-44-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28917-44-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,9,1 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28917-44:
(7*2)+(6*8)+(5*9)+(4*1)+(3*7)+(2*4)+(1*4)=144
144 % 10 = 4
So 28917-44-4 is a valid CAS Registry Number.

Dicarbonyl chelates from 1-cymantrenylalkylamides with the dendrite structure: formation, photochromism, and kinetics of dark reaction with carbon monoxide

Kelbysheva,Telegina,Abramova,Strelkova,Ikonnikov,Rodionov,Ezernitskaya,Lokshin,Loim

, p. 2646 - 2654 (2016/10/03)

Photolysis of carboxamides of the dendrite structure with aminomethyland 1-aminoethylcymantrenes leads to the formation of six-membered dicarbonyl chelates with the Mn—O bond which are stable in solutions. The chelates in the reversed dark reaction with carbon monoxide give the starting tricarbonyl complexes. The formation of the chelates and their dark reaction are accompanied by the reversible change of color by the compounds. The rate determining step of the thermal reaction of chelates with CO is a chelate ring opening with the ligand substitution by the SN1 mechanism. A possibility of solvent-free photoinduced ligand-exchange reaction in a number of cymantrene derivatives was demonstrated.

A new synthesis of 4′-resveratrol esters and evaluation of the potential for anti-depressant activity

Acerson, Mark J.,Fabick, Kimberly M.,Wong, Yong,Blake, Crystal,Lephart, Edwin D.,Andrus, Merritt B.

, p. 2941 - 2944 (2013/06/27)

The 4′-ester analog of the disease preventative resveratrol 1 (RV), 4′-acetyl-RV 2 along with 4′-pivaloate 13 and benzoate 14 RV were synthesized. The previously developed palladium catalyzed decarbonylative Heck coupling was used to assemble the stilbene core together with 3,5-dibenzyl protected phenol intermediates that allowed for efficient coupling and deprotection using boron trifluoride etherate. Studies with Long-Evans rats were performed to establish safety, toxicity, and behavioral parameters. In addition, the Porsalt forced-swim test was used to demonstrate anti-depressant activity.

Novel inhibitors of basal glucose transport as potential anticancer agents

Zhang, Weihe,Liu, Yi,Chen, Xiaozhuo,Bergmeier, Stephen C.

scheme or table, p. 2191 - 2194 (2010/06/15)

Cancer cells commonly show increased levels of glucose uptake and dependence. A potential strategy for the treatment of cancer may be the inhibition of basal glucose transport. We report here the synthesis of a small library of polyphenolic esters that inhibit basal glucose transport in H1299 lung and other cancer cells. These basal glucose transport inhibitors also inhibit cancer cell growth in H1299 cells, and these two activities appear to be correlated.
