83520-63-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83520-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,2 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83520-63:
(7*8)+(6*3)+(5*5)+(4*2)+(3*0)+(2*6)+(1*3)=122
122 % 10 = 2
So 83520-63-2 is a valid CAS Registry Number.

Aryloxybenzylidene ruthenium chelates: Synthesis, structure and catalytic activity in olefin metathesis

Z.ak, Patrycja,Rogalski, Szymon,Kubicki, Maciej,Przybylski, Piotr,Pietraszuk, Cezary

, p. 1131 - 1136 (2014)

New aryloxybenzylidene ruthenium chelates behave like a promising latent catalyst of olefin metathesis. The catalysts are characterised by substantial stability and catalytic inactivity in their dormant forms and a dramatic increase in activity after addi

3H-1,2-benzoxathiepine 2,2-dioxides: a new class of isoform-selective carbonic anhydrase inhibitors

Pustenko, Aleksandrs,Stepanovs, Dmitrijs,?alubovskis, Raivis,Vullo, Daniela,Kazaks, Andris,Leitans, Janis,Tars, Kaspars,Supuran, Claudiu T.

, p. 767 - 775 (2017/06/07)

A new chemotype with carbonic anhydrase (CA, EC 4.2.1.1) inhibitory action has been discovered, the homo-sulfocoumarins (3H-1,2-benzoxathiepine 2,2-dioxides) which have been designed considering the (sulfo)coumarins as lead molecules. An original synthetic strategy of a panel of such derivatives led to compounds with a unique inhibitory profile and very high selectivity for the inhibition of the tumour associated (CA IX/XII) over the cytosolic (CA I/II) isoforms. Although the CA inhibition mechanism with these new compounds is unknown for the moment, we hypothesize that it may be similar to that of the sulfocoumarins, i.e. hydrolysis to the corresponding sulfonic acids which thereafter anchor to the zinc-coordinated water molecule within the enzyme active site.
