Check Digit Verification of cas no

The CAS Registry Mumber 20458-90-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,5 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20458-90:
(7*2)+(6*0)+(5*4)+(4*5)+(3*8)+(2*9)+(1*0)=96
96 % 10 = 6
So 20458-90-6 is a valid CAS Registry Number.

Nickel-Catalyzed Reductive Thiolation of Unactivated Alkyl Bromides and Arenesulfonyl Cyanides

Rao, Weidong,Wang, Fei,Wang, Shun-Yi

, p. 8970 - 8979 (2021)

The cross-electrophile coupling between unactivated alkyl bromides with arenesulfonyl cyanides catalyzed by Ni(acac)2under reductive conditions to form unsymmetrical sulfides is developed. This approach for sulfide synthesis is practical, relies on available, unfunctionalized materials such as alkyl (pseudo)halides, and is scalable. This catalytic strategy provides a complementary method for the preparation of unsymmetrical alkyl-aryl sulfides under mild conditions with good functional group tolerance.

Synthesis of thioether andrographolide derivatives and their inhibitory effect against cancer cells

Liu, Yi,Liang, Ren-Ming,Ma, Qing-Ping,Xu, Kai,Liang, Xin-Yong,Huang, Wei,Sutton, Robert,Ding, Jie,O'Neil, Paul M.,Cheng, Chun-Ru

, p. 1268 - 1274 (2017/07/07)

A series of novel thioether andrographolide derivatives were synthesized by incorporating various aromatic (or heteroaromatic) substituents into C-12 or 14-OH. A total of 38 andrographolide derivatives were prepared and evaluated for their in vitro inhibi

Page/Page column 76, (2010/06/22)

The present invention concerns novel substituted aryl derivatives, their process of preparation and their use for inhibiting virus replication and for treating viral diseases or disorders such as HIV and/or HCV infection.

Some Sulfur-containing Quinoxalines (1)

Campaigne, E.,McLaughlin, Astley R.

, p. 623 - 628 (2007/10/02)

A series of quinoxalines having oxygen, chlorine or sulfur substituted at the 2-position and long-chain alkyl, alkylthio, arylthio, alkylthioalkyl or arylthioalkyl groups at the 3-position have been synthesized.
