128666-81-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128666-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,6 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128666-81:
(8*1)+(7*2)+(6*8)+(5*6)+(4*6)+(3*6)+(2*8)+(1*1)=159
159 % 10 = 9
So 128666-81-9 is a valid CAS Registry Number.

Synthesis and Anti-HBV Activity of Novel Substituted Pyrimidine Glycosides and Their Acyclic Analogues

Hawata,El-Sayed,Abdel-Rahman, Adel A.-H.

, p. 1734 - 1744 (2018/11/10)

New aryl substituted uracil and thiouracil glycosides are synthesized by glycosylation at N1 in the pyrimidine nucleus using glycopyranosyl halides in basic medium. In addition C-linked hydrazinyl acyclic sugar derivatives exhibiting different

Synthesis, antiplasmodial activity and mechanistic studies of pyrimidine-5-carbonitrile and quinoline hybrids

Kaur, Hardeep,Balzarini, Jan,De Kock, Carmen,Smith, Peter J.,Chibale, Kelly,Singh, Kamaljit

supporting information, p. 52 - 62 (2015/06/30)

Abstract A series of hybrids comprising of 5-cyanopyrimidine and quinoline moiety were synthesized and tested for in vitro antiplasmodial activity against NF54 and Dd2 strains of Plasmodium falciparum. Hybrid bearing m-nitrophenyl substituent at C-4 of py

Synthesis and antiviral activity of new substituted pyrimidine glycosides

Ramiz, Mahmoud M. M.,El-Sayed, Wael A.,Hagag, Ezzat,Abdel-Rahman, Adel A.-H.

experimental part, p. 1028 - 1038 (2011/11/29)

A number of N-substituted pyrimidine glycosides were synthesized by coupling reaction of the pyrimidine base with acetobromosugars followed by deprotection. The synthesized compounds were tested for their antiviral activity against Hepatitis B Virus (HBV). Plaque reduction infectivity assay was used to determine virus count reduction as a result of treatment with tested compounds which showed moderate to high anti viral activities.
