Check Digit Verification of cas no

The CAS Registry Mumber 1228093-49-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,0,9 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1228093-49:
(9*1)+(8*2)+(7*2)+(6*8)+(5*0)+(4*9)+(3*3)+(2*4)+(1*9)=149
149 % 10 = 9
So 1228093-49-9 is a valid CAS Registry Number.

Synthesis of polyfluorinated benzofurans

Politanskaya, Larisa,Troshkova, Nadezhda,Tretyakov, Evgeny,Xi, Chanjuan

, (2019/09/18)

A simple and efficient approach to the synthesis of fluorinated benzofurans including the Sonogashira cross-coupling of o-iodophenols with terminal Ph- and n-Bu-acetylenes, followed by intramolecular cyclization, in good to excellent yields is reported.

Efficient and reliable iodination and o-Methylation of fluorinated phenols

Francke, Robert,Schnakenburg, Gregor,Waldvogel, Siegfried R.

experimental part, p. 2357 - 2362 (2010/07/04)

Fluorinated phenols and other electron-deficient phenolic substrates are efficiently and cleanly iodinated by an iodine/ iodide mixture employing alkaline conditions. This protocol turned out to be the most practical for the generation of such highly fluorinated iodophenols. For later application in coupling processes the protection of the phenolic hydroxy moiety is often required. Therefore, a practical iodination and subsequent methylation sequence was elaborated providing the highly fluorinated anisoles with good to excellent yields. The developed method is applicable for a broad scope of fluorinated phenols and analogues.
