Methanesulfonothioic acid, S-(4-nitrophenyl) ester, also known as 4-nitrophenyl methanesulfonothioate, is a chemical compound with the molecular formula C7H6NO5S2. It is a yellow crystalline solid that is soluble in organic solvents such as ethanol and acetone. Methanesulfonothioic acid, S-(4-nitrophenyl) ester is primarily used as a reagent in organic synthesis, particularly in the preparation of various sulfur-containing compounds. It is also employed as a coupling reagent in peptide synthesis and as a selective inhibitor of certain enzymes. Due to its reactivity and potential toxicity, it is important to handle this chemical with care, following appropriate safety protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 2080-82-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,8 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2080-82:
(6*2)+(5*0)+(4*8)+(3*0)+(2*8)+(1*2)=62
62 % 10 = 2
So 2080-82-2 is a valid CAS Registry Number.

Antifungal thiosulfonates: Potency with some selectivity

Baerlocher, Felix Jakob,Baerlocher, Mark Otto,Chaulk, Crystal Lee,Langler, Richard Francis,MacQuarrie, Stephanie Lee

, p. 399 - 402 (2000)

A series of thiosulfonates have been prepared and tested against Aspergillus niger and Aspergillus flavus. In general, the thiosulfonates are moderate antifungal agents - more potent than corresponding inactive disulfides and less potent than corresponding very active fungitoxic disulfides. A pair of thiosulfonates show high selectivity, each killing only one kind of fungus. CSIRO 2000.

Page/Page column 30, (2010/11/30)

This invention is directed to novel and known stufur containing compounds and pharmaceutically acceptable salts thereof that have utility as antifungals and as antiproliferative agents against mammalian cells, in particular cancer cells and most particularly leukemia-derived cells. The invention provides a method for synthesizing certain of the sulfur containing compounds that is more efficient than previously known methods.
