27491-93-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 27491-93-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,4,9 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 27491-93:
(7*2)+(6*7)+(5*4)+(4*9)+(3*1)+(2*9)+(1*3)=136
136 % 10 = 6
So 27491-93-6 is a valid CAS Registry Number.

Preparation of halogeno(pentafluorophenyl)silanes (C6F5)nSiX4-n (X=F, Cl and Br; N=2, 3) from pentafluorophenyl(phenyl)silanes (C6F5)nSiPh4-n

Frohn,Lewin,Bardin

, p. 233 - 240 (2007/10/03)

Halogeno(pentafluorophenyl)silanes (C6F5)nSiX4-n (X=F, Cl and Br; n=2, 3) were prepared in good yields from the corresponding phenylsilanes (C6F5)nSiPh4-n by reactions with the electrophiles aHF, FSO3H, HCl-AlCl3 or with AlX3 (X=Cl, Br)-halogenated hydrocarbons. The relative leaving ability of the organyl groups (C6F5, C6H5, Me) bonded to the silicon atom and the strength of the electrophilic reagent are discussed.
