25636-63-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25636-63-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,6,3 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 25636-63:
(7*2)+(6*5)+(5*6)+(4*3)+(3*6)+(2*6)+(1*3)=119
119 % 10 = 9
So 25636-63-9 is a valid CAS Registry Number.

Copper-Catalyzed Oxyalkynylation of C-S Bonds in Thiiranes and Thiethanes with Hypervalent Iodine Reagents

Borrel, Julien,Pisella, Guillaume,Waser, Jerome

supporting information, p. 422 - 427 (2020/01/31)

We report the oxyalkynylation of thiiranes and thietanes using ethynylbenziodoxolone reagents (EBXs) to readily access functionalized building blocks bearing an alkynyl, a benzoate, and an iodide group. The reaction proceeds with high atom efficiency most

Synthesis of 3-alkyl(aryl)thietanes

Shevchenko,Volynskii

experimental part, p. 123 - 128 (2010/02/28)

A preparative procedure for the synthesis of thietanes bearing alkyl substituents in the β-position was developed. Using this procedure, 3-substituted thietanes can be obtained in four steps with an ultimate yield of > 50%. 3-R-thietanes (where R = CH3, C4H9, C5H11, C6H13, C6H 5) and the corresponding sulfoxides and sulfones were synthesized and examined. The feasibility of preparation of gem-3,3-substituted thietanes was exemplified by the synthesis of 3,3-dihexylthietane.
