Check Digit Verification of cas no

The CAS Registry Mumber 29938-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,9,3 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 29938-41:
(7*2)+(6*9)+(5*9)+(4*3)+(3*8)+(2*4)+(1*1)=158
158 % 10 = 8
So 29938-41-8 is a valid CAS Registry Number.

Regio- and Stereoselective Synthesis of Sulfur-Bearing Four-Membered Heterocycles: Direct Access to 2,4-Disubstituted Thietane 1-Oxides

Degennaro, Leonardo,Carroccia, Laura,Parisi, Giovanna,Zenzola, Marina,Romanazzi, Giuseppe,Fanelli, Flavio,Pisano, Luisa,Luisi, Renzo

, p. 12201 - 12211 (2015)

Starting from readily available C2-substituted thietane 1-oxides, a straightforward synthesis of new C2,C4-disubstituted thietane 1-oxides has been developed by using a lithiation/electrophilic trapping sequence. The chemical and configurational stability of lithiated C2-substituted thietane 1-oxides has been investigated as well as the stereochemical implications for this process. The results demonstrate that a stereoselective functionalization at the C2, C4 positions of a thietane is feasible, leaving intact the four-membered ring.

Synthesis of 2-alkyl(aryl)thietanes

Volynskii,Shevchenko

, p. 109 - 117 (2008/02/03)

Thietane and its 2-substituted derivatives were synthesized. A general preparation procedure for the synthesis of thietanes bearing alkyl and aryl substituents in the α-position was developed. Using this procedure, 2-substituted thietanes can be obtained from cheap and easily accessible raw materials in three steps. 2-R-Thietanes (where R = H, CH3, C 4H9, C5H11, C6H 13, C6H5) and the corresponding sulfoxides and sulfones were synthesized and examined. Intermediate and by-products of the synthesis were studied. Nauka/Interperiodica 2007.

Preparation of 2-(3-Hydroxyalkylthio)benzoxazoles and their Conversion into Thietanes

Ikemizu, Dai,Matsuyama, Ayako,Takemura, Kazunori,Mitsunobu, Oyo

, p. 1247 - 1248 (2007/10/03)

Reaction of primary or secondary 1,3-diols with dibenzoxazol-2-yl disulfide and tributylphosphine or triphenylphosphine selectively gave 2-(3-hydroxyalkylthio)benzoxazoles which, on treatment with KH, were converted into the corresponding thietanes. 2,2-Dibenzylthietane-1-oxide reacted with silylated purines and pyrimidines in the presence of TMSOTf and ZnI2 to give the corresponding thietane nucleosides in 17-69% yields.
