197636-95-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 197636-95-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,6,3 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 197636-95:
(8*1)+(7*9)+(6*7)+(5*6)+(4*3)+(3*6)+(2*9)+(1*5)=196
196 % 10 = 6
So 197636-95-6 is a valid CAS Registry Number.

Formation of a tris(catecholato) iron(iii) complex with a nature-inspired cyclic peptoid ligand

Oh, Jinyoung,Kang, Dahyun,Hong, Sugyeong,Kim, Sun H.,Choi, Jun-Ho,Seo, Jiwon

, p. 3459 - 3463 (2021)

Siderophore-mimicking macrocyclic peptoids were synthesized. Peptoid3with intramolecular hydrogen bonds showed an optimally arranged primary coordination sphere leading to a stable catecholate-iron complex. The tris(catecholato) structure of 3-Fe(iii) was determined with UV-vis, fluorescence, and EPR spectroscopies and DFT calculations. The iron binding affinity was comparable to that of deferoxamine, with enhanced stability upon air exposure.

Peptoid-based siderophore mimics as dinuclear Fe3+chelators

Costabile, Chiara,D'Amato, Assunta,De Riccardis, Francesco,Della Sala, Giorgio,Ghosh, Pritam,Izzo, Irene,Maayan, Galia

, p. 6020 - 6029 (2020/05/25)

A practical synthesis of preorganized tripodal enterobactin/corynebactin-type ligands (consisting of aC3-symmetric macrocyclic peptoid core, three catecholamide coordinating units, and C2, C4, and C6spacers) is

Synthesis of bifunctional biscatecholamine chelators for uranium decorporation

Lei, Shan,Jin, Bo,Zhang, Qingchun,Zhang, Zhichao,Wang, Xiaofang,Peng, Rufang,Chu, Shijin

, p. 387 - 395 (2016/10/13)

New 1,3-dicarbonyl biscatecholamide ligands were synthesized to decorporate uranium for nuclear contamination. The derivatives were characterized via1H NMR spectroscopy,13C NMR spectroscopy, FTIR spectroscopy and mass spectrometry. The complexation abilities of ligands 8a–8d with UO22+, Cu2+and Zn2+were determined through spectrophotometric and potentiometric titrations technology. The antioxidant capacities of the ligands were assessed through DPPH antioxidant assay. Results indicated that ligands 8a–8d are potential decorporating agents for uranyl ion (pUO2up to 22.41) and copper(II) ion (pCu up to 17.71) without depletion of the essential element zinc (pZn lower than 7.48).
