22131-84-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22131-84-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,3 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22131-84:
(7*2)+(6*2)+(5*1)+(4*3)+(3*1)+(2*8)+(1*4)=66
66 % 10 = 6
So 22131-84-6 is a valid CAS Registry Number.

Synthesis and structure-activity relationships of novel amino/nitro substituted 3-arylcoumarins as antibacterial agents

Matos, Maria J.,Vazquez-Rodriguez, Saleta,Santana, Lourdes,Uriarte, Eugenio,Fuentes-Edfuf, Cristina,Santos, Ysabel,Munoz-Crego, Angeles

, p. 1394 - 1404 (2013/04/23)

A new series of amino/nitro-substituted 3-arylcoumarins were synthesized and their antibacterial activity against clinical isolates of Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative) was evaluated. Some of these molecules exhibited antibacterial activity against S. aureus comparable to the standards used (oxolinic acid and ampicillin). The preliminary structure-activity relationship (SAR) study showed that the antibacterial activity against S. aureus depends on the position of the 3-arylcoumarin substitution pattern. With the aim of finding the structural features for the antibacterial activity and selectivity, in the present manuscript different positions of nitro, methyl, methoxy, amino and bromo substituents on the 3-arylcoumarin scaffold were reported.

Synthesis and characterization of dimaleimide fluorogens designed for specific labeling of proteins

Girouard, Stephane,Houle, Marie-Helene,Grandbois, Alain,Keillor, Jeffrey W.,Michnick, Stephen W.

, p. 559 - 566 (2007/10/03)

A series of aromatic compounds were prepared bearing two maleimide groups attached directly to the fluorescent cores. The resulting derivatives do not fluoresce until the maleimide groups undergo their typical thiol addition reaction, thus removing their
