1005769-62-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1005769-62-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,5,7,6 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1005769-62:
(9*1)+(8*0)+(7*0)+(6*5)+(5*7)+(4*6)+(3*9)+(2*6)+(1*2)=139
139 % 10 = 9
So 1005769-62-9 is a valid CAS Registry Number.

Catalytic Alkynylation of Polyfluoroarenes by Amide Base Generated In Situ

Shigeno, Masanori,Okawa, Takuya,Imamatsu, Masaya,Nozawa-Kumada, Kanako,Kondo, Yoshinori

, p. 10294 - 10297 (2019)

We herein demonstrate that the amide base generated in situ from CsF and N(TMS)3 catalyzes the deprotonative coupling reactions of terminal alkynes with polyfluoroarenes, wherein mono- and dialkynylations occur efficiently for penta- and hexafluorobenzenes, respectively. Tetraalkynylated products could also be synthesized from dialkynylated compounds.

Transition-metal-free synthesis of poly(phenylene ethynylene)s with alternating aryl-perfluoroaryl units

Dutta, Tanmoy,Woody, Kathy B.,Watson, Mark D.

, p. 452 - 453 (2008/09/19)

A catalytic amount of fluoride salt is all that is required to generate high molecular weight poly(phenylene ethynylene)s from silylacetylene-functionalized monomers and C6F6. The sole side product is gaseous fluorotrimethylsilane an
