34009-02-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34009-02-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,0,0 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34009-02:
(7*3)+(6*4)+(5*0)+(4*0)+(3*9)+(2*0)+(1*2)=74
74 % 10 = 4
So 34009-02-4 is a valid CAS Registry Number.

Palladium-catalyzed direct α-arylation of methyl sulfones with aryl bromides

Zheng, Bing,Jia, Tiezheng,Walsh, Patrick J.

supporting information, p. 1690 - 1693 (2013/06/26)

A direct and efficient approach for palladium-catalyzed arylation of aryl and alkyl methyl sulfones with aryl bromides has been developed. The catalytic system affords arylated sulfones in good to excellent yields (73-90%).

Cyanuric chloride promoted oxidation of sulfides to sulfoxides or sulfones in the presence of hydrogen peroxide

Lakouraj, Moslem Mansour,Abdi, Hamid,Hasantabar, Vahid

experimental part, p. 435 - 441 (2012/06/16)

Aromatic and aliphatic sulfides are readily oxidized to sulfoxides or sulfones in high yield with 35% hydrogen peroxide in the presence of cyanuric chloride (CC) as an efficient activator. The oxidation of sulfides proceeds at room temperature and the corresponding sulfoxides or sulfones was selectively obtained by controlling the amounts of H2O2 and CC. Various sulfides possessing functional groups such as hydroxyl, methoxy, nitrile, aldehyde and olefinic double bond were successfully and selectively oxidized without affecting sensitive functionalities.
