280137-25-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 280137-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,0,1,3 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 280137-25:
(8*2)+(7*8)+(6*0)+(5*1)+(4*3)+(3*7)+(2*2)+(1*5)=119
119 % 10 = 9
So 280137-25-9 is a valid CAS Registry Number.

Searching for new chemosensitizers of bacterial multidrug resistance (MDR), chemical modifications of (Z)-5-(4-chlorobenzylidene)-2-(4-methylpiperazin-1-yl)-3H-imidazol-4(5H)-one (6) were performed. New compounds (7–17), with fused aromatic rings at posit

Bicyclic imidazole-4-one derivatives: A new class of antagonists for the orphan G protein-coupled receptors GPR18 and GPR55

, p. 632 - 649 (2014/05/06)

GPR18 and GPR55 are orphan G protein-coupled receptors (GPCRs) that interact with certain cannabinoid (CB) receptor ligands. In the present study bicyclic imidazole-4-one derivatives were discovered as new scaffolds for the development of antagonists for

The synthesis of 2-alkylthio-3-alkyl-5-arylmethylidene-4H-imidazol-4-ones

Sun, Yong,Gao, Li-Ping,Guo, Zhi-Qiang,Ding, Ming-Wu

, p. 2109 - 2116 (2007/10/03)

2-alkylthio-3-alkyl-5-arylmethylidene-4H-imidazol-4-ones were synthesized by the S-alkylation and N-alkylation of 2-thioxo-5-arylmethylidene-4- imidazolidinones, which were obtained via a tandem aza-Wittig reaction of vinyliminophosphoranes, carbon disulf
