Check Digit Verification of cas no

The CAS Registry Mumber 949111-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,9,1,1 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 949111-71:
(8*9)+(7*4)+(6*9)+(5*1)+(4*1)+(3*1)+(2*7)+(1*1)=181
181 % 10 = 1
So 949111-71-1 is a valid CAS Registry Number.

Design, Synthesis, and Evaluation of Fluorinated Radioligands for Myelin Imaging

Myelination is one of the fundamental processes in vertebrates. A major challenge is to quantitatively image myelin distribution in the central nervous system. For this reason, we designed and synthesized a series of fluorinated radioligands that can be radiolabeled as radiotracers for positron emission tomography (PET) imaging of myelin. These newly developed radioligands readily penetrate the blood-brain barrier and selectively bind to myelin membranes in the white matter region. Structure-activity relationship studies of such ligands suggested that optimal permeability could be achieved with calculated lipophilicty in the range of 3-4. After radiolabeling with fluorine-18, the brain uptake and retention of each radioligand were determined by microPET/CT imaging studies. These pharmacokinetic studies led us to identify a lead compound ([18F]FMeDAS, 32) with promising in vivo binding properties, which was subsequently validated by ex vivo autoradiography.
