2H-Thiopyran, 3,6-dihydro-2-phenyl-1,1-dioxide is a complex organic chemical compound with the molecular formula C10H10O2S. It is a derivative of thiopyran, which is a heterocyclic compound containing a sulfur atom in the ring structure. This specific compound features a phenyl group attached to the thiopyran ring, and it has a 1,1-dioxide functional group, indicating the presence of two oxygen atoms bonded to the same carbon atom. The 3,6-dihydro prefix suggests that there are two hydrogen atoms added to the molecule, which can affect its reactivity and stability. 2H-Thiopyran, 3,6-dihydro-2-phenyl-, 1,1-dioxide may be used in the synthesis of various pharmaceuticals, agrochemicals, or other specialty chemicals due to its unique structure and properties.

Check Digit Verification of cas no

The CAS Registry Mumber 115691-17-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,6,9 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 115691-17:
(8*1)+(7*1)+(6*5)+(5*6)+(4*9)+(3*1)+(2*1)+(1*7)=123
123 % 10 = 3
So 115691-17-3 is a valid CAS Registry Number.

, p. 427 - 430 (2007/10/03)

A general and highly efficient synthesis of cyclic sulfones based on ring-closing metathesis has been developed. The synthetic utility of the resulting cyclic sulfones was demonstrated by their participation in stereoselective Diels-Alder reactions and transformation to cyclic dienes by the Ramberg-Baecklund reaction.

Trimethylsilylphenyl- and triphenylsilylphenyl thioketones easily undergo -cycloadditions with cyclic and open chain 1,3-dienes at room temperature to give silylated thiabicycloheptenes and dihydrothiopyrans in very good yields.With cyclopentadiene the reaction produces exclusively the endo-silylated adducts.Sulphur oxidation and desilylation of the adducts were also investigated.
