158554-93-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 158554-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,5,5 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 158554-93:
(8*1)+(7*5)+(6*8)+(5*5)+(4*5)+(3*4)+(2*9)+(1*3)=169
169 % 10 = 9
So 158554-93-9 is a valid CAS Registry Number.

Effect of added benzoic acid on the phase-transfer catalysed permanganate oxidation of organosulfur compounds

Aitken, R. Alan,Mesher, Shaun T. E.,Ross, Fiona C.,Ryan, Bruce M.

, p. 787 - 791 (2007/10/03)

The addition of benzoic acid in the oxidation of a range of sulfides and thiazolidinethiones using KMnO4 under phase-transfer conditions provides a convenient and high yielding procedure for formation of the corresponding sulfones, thiazolidinones and thiazolidinone S,S-dioxides.

Unexpected Thermal Extrusion of CO2 from 3-Benzylthiazolidin-2-one 1,1-Dioxides to Give 2-Phenylthiazolines and Thiazoles

Aitken, R. Alan,Armstrong, David P.,Mesher, Shaun T. E.,Galt, Ronald H. B.

, p. 6143 - 6146 (2007/10/02)

Flash vacuum pyrolysis of a series of chiral 3-benzylthiazolidin-2-one 1,1-dioxides 5, readily prepared from amino acids, results mainly in loss of SO2 to give an alkene and benzyl isocyanate, but a significant minor pathway involves unexpected loss of CO2 and water to give 2-phenylthiazolines 13 and derived thiazoles.
