221121-48-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 221121-48-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,1,2 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 221121-48:
(8*2)+(7*2)+(6*1)+(5*1)+(4*2)+(3*1)+(2*4)+(1*8)=68
68 % 10 = 8
So 221121-48-8 is a valid CAS Registry Number.

Synthesis and biological evaluation of 6-substituted 5-Alkyl-2-(phenylaminocarbonylmethylthio)pyrimidin-4(3H)-ones as potent HIV-1 NNRTIs

Yu, Mingyan,Li, Zhenyu,Liu, Shuai,Fan, Erkang,Pannecouque, Christophe,DeClercq, Erik,Liu, Xinyong

experimental part, p. 826 - 833 (2012/01/14)

A series of new 5-alkyl-2-phenylaminocarbonylmethylthiopyrimidin-4(3H)-ones bearing variously substituted arylmethyl moieties at the C6 position of the pyrimidine ring were synthesized and evaluated for anti-HIV activity in MT-4 cells. Most of these new c

experimental part, p. 4641 - 4652 (2009/07/04)

A series of dihydro-alkylthio-benzyl-oxopyrimidines (S-DABOs) bearing a 2-aryl-2-oxoethylsulfanyl chain at pyrimidine C2, an alkyl group at C5, and a 2,6-dichloro-, 2-chloro-6-fluoro-, and 2,6-difluoro-benzyl substitution at C6 (oxophenethyl-S-DABOs, 6-8)

Dihydro-alkylthio-benzyl-oxopyrimidines as inhibitors of reverse transcriptase: Synthesis and rationalization of the biological data on both wild-type enzyme and relevant clinical mutants
