Check Digit Verification of cas no

The CAS Registry Mumber 41280-62-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,2,8 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 41280-62:
(7*4)+(6*1)+(5*2)+(4*8)+(3*0)+(2*6)+(1*2)=90
90 % 10 = 0
So 41280-62-0 is a valid CAS Registry Number.

Transition-Metal-Free HFIP-Mediated Organo Chalcogenylation of Arenes/Indoles with Thio-/Selenocyanates

Kalaramna, Pratibha,Goswami, Avijit

, p. 9317 - 9327 (2021)

We have developed a protocol for the synthesis of diaryl thio-/selenoethers by the reaction of aryl chalcogenocyanates with electron rich arenes/hetero arenes via HFIP promoted C-H activation. The reaction produces chalcogenides in good to excellent yields under mild conditions without the need of a transition metal as a catalyst. The HFIP-mediated reactions tolerated a wide range of functional groups and set the stage for the synthesis of diversely decorated chalcogenides. A mechanism involving activation of the C-H bond through hydrogen bonding is proposed.

Metal-and oxidant-free electrochemical synthesis of aryl sulfides

Wang, Xin-Xing,Chen, Cheng,Shi, Hai-Zhu,Zhang, Guo-Wei,Tang, Yu,Zhang, Chun-Gu,Wu, Ming-Yu,Feng, Shun

, (2021/02/26)

A metal- and oxidant-free electrochemical synthesis of aryl sulfides was developed through a C–H sulfidation reaction of arenes and disulfides. Compared with traditional organic synthesis methods, this direct electrochemical approach efficiently generates aryl sulfides under catalyst- and oxidant-free conditions with the superiorities of wide substrate compatibility, mild reaction condition and waster free. At room temperature, various aryl thiols could be transformed smoothly in an undivided cell. Based on cyclic voltammetry (CV) and control experiments, the possible reaction mechanism was also proposed. The gram-scale synthesis emphasizes the practicability of this electrochemical strategy.

Palladium(II)/Copper(II)-Catalyzed C–H Sulfidation or Selenation of Arenes Leading to Unsymmetrical Sulfides and Selenides

Nishino, Kota,Tsukahara, Shouya,Ogiwara, Yohei,Sakai, Norio

supporting information, p. 1588 - 1593 (2019/02/09)

A novel palladium(II)/copper(II)-catalyzed sulfidation of the C–H bond in electron-rich arenes and in pentafluorobenzene with disulfides was developed. This catalytic system can be used to efficiently produce various types of either unsymmetrical aryl sulfides or alkyl aryl sulfides. The present protocol could also be applied to the direct preparation of unsymmetrical aryl selenides via C–H selenation.
