2785-76-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2785-76-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2785-76:
(6*2)+(5*7)+(4*8)+(3*5)+(2*7)+(1*6)=114
114 % 10 = 4
So 2785-76-4 is a valid CAS Registry Number.

Inhibition of Urease, a Ni-Enzyme: The Reactivity of a Key Thiol With Mono- and Di-Substituted Catechols Elucidated by Kinetic, Structural, and Theoretical Studies

Mazzei, Luca,Contaldo, Umberto,Musiani, Francesco,Cianci, Michele,Bagnolini, Greta,Roberti, Marinella,Ciurli, Stefano

, p. 6029 - 6035 (2021/02/09)

The inhibition of urease from Sporosarcina pasteurii (SPU) and Canavalia ensiformis (jack bean, JBU) by a class of six aromatic poly-hydroxylated molecules, namely mono- and dimethyl-substituted catechols, was investigated on the basis of the inhibitory efficiency of the catechol scaffold. The aim was to probe the key step of a mechanism proposed for the inhibition of SPU by catechol, namely the sulfanyl radical attack on the aromatic ring, as well as to obtain critical information on the effect of substituents of the catechol aromatic ring on the inhibition efficacy of its derivatives. The crystal structures of all six SPU-inhibitors complexes, determined at high resolution, as well as kinetic data obtained on JBU and theoretical studies of the reaction mechanism using quantum mechanical calculations, revealed the occurrence of an irreversible inactivation of urease by means of a radical-based autocatalytic multistep mechanism, and indicate that, among all tested catechols, the mono-substituted 3-methyl-catechol is the most efficient inhibitor for urease.

An expedient one-pot entry to catecholestrogens and other catechol compounds via IBX-mediated phenolic oxygenation

Pezzella, Alessandro,Lista, Liliana,Napolitano, Alessandra,D'Ischia, Marco

, p. 3541 - 3544 (2007/10/03)

A one-pot procedure for the preparation of catecholestrogens in over 90% yield is reported, involving oxygenation of 17β-estradiol or estrone with o-iodoxybenzoic acid (IBX) followed by reduction with methanolic NaBH 4. The procedure, which was extended to the o-hydroxylation of a number of representative phenols in good-to-high yields, expands significantly the scope of phenolic oxidation mediated by IBX.
