Check Digit Verification of cas no

The CAS Registry Mumber 1393123-19-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,1,2 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1393123-19:
(9*1)+(8*3)+(7*9)+(6*3)+(5*1)+(4*2)+(3*3)+(2*1)+(1*9)=147
147 % 10 = 7
So 1393123-19-7 is a valid CAS Registry Number.

Alcohol-Enhanced Cu-Mediated Radiofluorination

Zischler, Johannes,Kolks, Niklas,Modemann, Daniel,Neumaier, Bernd,Zlatopolskiy, Boris D.

supporting information, p. 3251 - 3256 (2017/03/17)

The potential of many 18F-labeled (hetero)aromatics for applications in positron emission tomography remains underexplored because convenient procedures for their radiosynthesis are lacking. Consequently, simple methods to prepare radiofluorinated (hetero)arenes are highly sought after. Herein, we report the beneficial effect of primary and secondary alcohols on Cu-mediated 18F-labeling. This observation contradicts the assumption that such alcohols are inappropriate solvents for aromatic fluorination. Therefore, we developed a protocol for rapid radiolabeling of an extraordinarily broad scope of boronic and stannyl substrates under general reaction conditions. Notably, radiofluorinated indoles, phenols, and anilines were synthesized directly from the corresponding unprotected precursors. Furthermore, the novel method enabled the preparation of radiofluorinated tryptophans, [18F]F-DPA, [18F]DAA1106, 6-[18F]FDA, and 6-[18F]FDOPA.
