52154-24-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52154-24-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,5 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52154-24:
(7*5)+(6*2)+(5*1)+(4*5)+(3*4)+(2*2)+(1*4)=92
92 % 10 = 2
So 52154-24-2 is a valid CAS Registry Number.

The synthesis of chiral β-ketosulfoxides by enantioselective oxidation and their stereocontrolled reduction to β-hydroxysulfoxides

Cardellicchio, Cosimo,Omar, Omar Hassan,Naso, Francesco,Capozzi, Maria Annunziata M.,Capitelli, Francesco,Bertolasi, Valerio

, p. 223 - 229 (2007/10/03)

Various chiral non-racemic β-ketosulfoxides, a class of compounds frequently used in asymmetric synthesis, were prepared in good yields by tert-butyl hydroperoxide oxidation of the corresponding sulfides in the presence of a complex between titanium and (

Bis(1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane) persulfate: A mild and efficient oxidant for cleavage of oxime double bonds under anhydrous conditions

Hajipour,Mohammadpoor-Baltork,Kianfar

, p. 221 - 224 (2007/10/03)

Bis(1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane)persulfate (BAABCPS) 1 readily prepared as orange solid from commercially available 1,4- diazabicyclo[2.2.2]octane (DABCO) and potassium persulfate, converts oximes and α-sulfinyl oximes to the corresponding carbonyl compounds and β-keto sulfoxides respectively, the yields and enantiomeric purity are excellent.

1-Benzyl-4-aza-1-azoniabicyclo[2.2.2]octane Periodate: A Mild and Efficient Oxidant for the Cleavage of Oxime Double Bonds under Anhydrous Conditions

Hajipour, Abdol Reza,Mahboubghah, Nasrien

, p. 122 - 123 (2007/10/03)

1-Benzyl-4-aza-1-azoniabicyclo[2.2.2]octane periodate (BAABCP) (1), readily prepared from commercially available 1,4-diazabicyclo[2.2.2]octane (DABCO) and sodium periodate, converts oximes and α-sulfinyl oximes to the corresponding carbonyl compounds and β-keto sulfoxides, respectively, in high yields and high enantiomeric purity.
