Uses
Different sources of media describe the Uses of 15220-11-8 differently. You can refer to the following data:
1. Met-enkephalin analog found in opioid extracts of brain and adrenal chromaffin cells that is an artifact generated by trichloroacetic acid extraction. MUS is used as a fluorimetric substrate for arylsulphatase enzyme. Subsitution of the hydroxyl group of 4-Methylumbelliferyl sulfate potassium salt causes the excitation wavelength of the umbelliferone to shift to shorter values and also brings about a decrease in fluorescence. Fluorescence: max. Abs = 334 mm; max. Em. = 370 mm
2. 4-Methylumbelliferyl sulfate potassium salt is a fluorometric substrate for the determination of sulfatase. This substrate has been used in the discovery of tyrosine sulfotransferase inhibitors, particularly in P-selectin glycoprotein ligand-1 binding. This compound is virtually non-fluorescent until cleavage by sulfatase enzymes, then emits blue fluorescence (450 nm) with excitation at 360 nm. Use of this compound in high-throughput fluorescence based screening led to the discovery of several potent beta-arylsulfotransferase IV (beta-AST-IV) inhibitors.
Check Digit Verification of cas no
The CAS Registry Mumber 15220-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,2 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15220-11:
(7*1)+(6*5)+(5*2)+(4*2)+(3*0)+(2*1)+(1*1)=58
58 % 10 = 8
So 15220-11-8 is a valid CAS Registry Number.
