28215-02-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28215-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,1 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 28215-02:
(7*2)+(6*8)+(5*2)+(4*1)+(3*5)+(2*0)+(1*2)=93
93 % 10 = 3
So 28215-02-3 is a valid CAS Registry Number.

NFSI-catalyzed S[sbnd]S bond exchange reaction for the synthesis of unsymmetrical disulfides

Hu, Qingyue,Li, Zheng-Yi,Song, Mengjie,Sun, Xiaoqiang,Yang, Ke

supporting information, (2022/01/26)

The metal-free S[sbnd]S bond exchange reaction of symmetrical disulfides catalyzed by NFSI is described. This novel protocol provides a facile and efficient approach to accessing important unsymmetrical disulfides. Furthermore, this strategy could also be utilized in the late-stage functionalization of amino acids, drugs, and natural products. The broad substrate scope, good functional group tolerance and easy accessibility of catalyst indicate that this strategy affords a green and practical complementary method to various unsymmetrical disulfides.

Ortho Effects in Organic Molecules on Electron Impact: 21 - Oxygen Transfers from the Ortho Nitro Group to Sulphur in N-Aryl-2-nitrobenzenesulphenamides and Phenyl-2-nitrophenyl Disulphide

Ramana, D. V.,Sundaram, N.,George, M.

, p. 926 - 930 (2007/10/02)

Fragment ions arising as a result of oxygen transfer from the nito group to sulphur have been noticed in N-aryl-2-nitrobenzenesulphenamides and phenyl-2-nitrophenyl disulphide.In the case of the former a double oxygen transfer to the sulphur has been noti
