Check Digit Verification of cas no

The CAS Registry Mumber 83852-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,8,5 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83852-28:
(7*8)+(6*3)+(5*8)+(4*5)+(3*2)+(2*2)+(1*8)=152
152 % 10 = 2
So 83852-28-2 is a valid CAS Registry Number.

Copper(ii) complexes of macrocyclic and open-chain pseudopeptidic ligands: synthesis, characterization and interaction with dicarboxylates

Faggi, Enrico,Gavara, Raquel,Bolte, Michael,Fajarí, Lluís,Juliá, Luís,Rodríguez, Laura,Alfonso, Ignacio

, p. 12700 - 12710 (2015)

Mono- and dinuclear Cu(ii) complexes were prepared with pseudopeptidic open chain and macrocyclic ligands, respectively. They were characterized by UV-vis spectroscopy, EPR, HRMS and X-ray diffraction. The Cu(ii) cation is coordinated by two amines and tw

Efficient macrocyclization of U-turn preorganized peptidomimetics: The role of intramolecular H-bond and solvophobic effects

Becerril, Jorge,Bolte, Michael,Burguete, M. Isabel,Galindo, Francisco,Garcia-Espana, Enrique,Luis, Santiago V.,Miravet, Juan F.

, p. 6677 - 6686 (2007/10/03)

Simple peptidomimetic molecules derived from amino acids were reacted with meta- and parabis(bromomethyl) benzene in acetonitrile to very efficiently yield macrocyclic structures. The cyclization reaction does not require high dilution techniques and seems to be insensitive to the size of the formed macrocycle. The analysis of data obtained by 1H NMR, single-crystal X-ray diffraction, fluorescence measurements, and molecular mechanics indicate that folded conformations can preorganize the system for an efficient cyclization. The role played by intramolecular hydrogen-bonding and solvophobic effects in the presence of folded conformations is analyzed.
