5523-99-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5523-99-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,2 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5523-99:
(6*5)+(5*5)+(4*2)+(3*3)+(2*9)+(1*9)=99
99 % 10 = 9
So 5523-99-9 is a valid CAS Registry Number.

Iron-catalyzed oxidative functionalization of C(sp3)-H bonds under bromide-synergized mild conditions

Yu, Han,Zhao, Qixin,Wei, Zheyu,Wu, Zhikang,Li, Qi,Han, Sheng,Wei, Yongge

supporting information, p. 7840 - 7843 (2019/07/12)

An efficient oxidation and functionalization of C-H bonds with an inorganic-ligand supported iron catalyst and hydrogen peroxide to prepare the corresponding ketones was achieved using the bromide ion as a promoter. Preliminary mechanistic investigations indicated that the bromide ion can bind to FeMo6 to form a supramolecular species (FeMo6·2Br), which can effectively catalyze the reaction.

AN INVESTIGATION OF THE ELECTRON TRANSFER PROPERTIES OF MODIFIED ORGANOCOPPER REAGENTS AND HIGHER-ORDER CUPRATES

Smith, Robin A. J.,Vellekoop, A. Samuel

, p. 517 - 522 (2007/10/02)

The electron transfer properties of organocopper reagents are attenuated on introduction of BF3OEt2 or Me3SiCl.The results are interpreted in concordance with current mechanistic proposals.Higher-order CuCN-based cuprates show significant electron transfer ability, in contrast to the related lower-order cuprates.
