20298-86-6 Usage
Enzyme inhibitor
This linear tetrapyrrole (FW = 559.64 g/mol) is a prosthetic group of blue, highly fluorescent photoreceptor pigments (phycocyanins) found in certain algae. It is soluble in water and polar organic solvents. Phycocyanins, found in Cyanophyta, are proteins, which typically contain three molecules of covalently bound phycocyanobilin per subunit. One molecule of phycocyanobilin is bound per molecule of allophycocyanin, found in Cyanophyta and Rhodophyta. Phycocyanins and their chromophore phycocyanobilin are peroxy radical scavengers and inhibits ONOO–- mediated biological effects. Target(s): cyclooxygenase-2, inhibited by C-phycocyanin and poorly by phycocyanobilin.
Check Digit Verification of cas no
The CAS Registry Mumber 20298-86-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,9 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20298-86:
(7*2)+(6*0)+(5*2)+(4*9)+(3*8)+(2*8)+(1*6)=106
106 % 10 = 6
So 20298-86-6 is a valid CAS Registry Number.

The detection of Hg2+ by cyanobacteria in aqueous media
Suresh, Moorthy,Mishra, Sanjiv K.,Mishra, Sandhya,Das, Amitava
experimental part, p. 2496 - 2498 (2009/09/30)
A tetrapyrrole-based chromophore was obtained through the methanolysis of C-phycocyanin extracted from Spirulina platensis, and was found to act as a selective receptor for Hg2+ at physiological pH conditions. The Royal Society of Chemistry 200
