Check Digit Verification of cas no

The CAS Registry Mumber 17067-70-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,6 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17067-70:
(7*1)+(6*7)+(5*0)+(4*6)+(3*7)+(2*7)+(1*0)=108
108 % 10 = 8
So 17067-70-8 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 (1998)

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.
