1051899-19-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1051899-19-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,1,8,9 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1051899-19:
(9*1)+(8*0)+(7*5)+(6*1)+(5*8)+(4*9)+(3*9)+(2*1)+(1*9)=164
164 % 10 = 4
So 1051899-19-4 is a valid CAS Registry Number.

Development of indazolylpyrimidine derivatives as high-affine EphB4 receptor ligands and potential PET radiotracers

Ebert, Kristin,Wiemer, Jens,Caballero, Julio,K?ckerling, Martin,Steinbach, J?rg,Pietzsch, Jens,Mamat, Constantin

, p. 6025 - 6035 (2015)

Due to their essential role in the pathogenesis of cancer, members of the Eph (erythropoietin-producing hepatoma cell line-A2) receptor tyrosine kinase family represent promising candidates for molecular imaging. Thus, the development and preparation of novel radiotracers for the noninvasive imaging of the EphB4 receptor via positron emission tomography (PET) is described. First in silico investigations with the indazolylpyrimidine lead compound which is known to be highly affine to EphB4 were executed to identify favorable labeling positions for an introduction of fluorine-18 to retain the affinity. Based on this, reference compounds as well as precursors were developed and labeled with carbon-11 and fluorine-18, respectively. For this purpose, a protecting group strategy essentially had to be generated to prevent unwanted methylation and to enable the introduction of fluorine-18. Further, a convenient radiolabeling strategy using [11C]methyl iodide was established which afforded the isotopically labeled radiotracer in 30-35% RCY (d.c.) which is identical with the original inhibitor molecule. A spiro ammonium precursor was prepared for radiolabeling with fluorine-18. Unfortunately, the labeling did not lead to the desired 18F-radiotracer under the chosen conditions.
