Check Digit Verification of cas no
The CAS Registry Mumber 13465-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,6 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13465-84:
(7*1)+(6*3)+(5*4)+(4*6)+(3*5)+(2*8)+(1*4)=104
104 % 10 = 4
So 13465-84-4 is a valid CAS Registry Number.

Chemical vapour transport of intermetallic phases, II: The system Fe-Si

Five phases exist in the system Fe-Si: Fe3Si, Fe2Si, Fe5Si3, FeSi, α- and β-FeSi2. All phases could be prepared by chemical transport with iodine as transport agent in the temperature range between T1 (700 °C) and T2 (1030 °C). In a attempted systematic clarification of the chemical transport reactions of all phases in the system, the effective transport equilibria were determined. Thermodynamic calculations show satisfactory agreement between calculation and experiment.

Reactions of SiF2 with halogens have been reinvestigated by both co-condensation and gas-phase methods.The co-condensation method yields a number of fluorohalogenosilanes including mono-, di-, and higher silane derivatives.These compounds contain SiF, SiF2, and SiF3 units.The reactivity towards SiF2 decreases from chlorine through bromine to iodine.While chlorine and bromine give rise to a number of fluorohalogenosilanes, iodine yields only the monosilane derivatives.In contrast, the gas-phase reaction do not progress to any appreciable extent.The products have been characterized by mass spectrometry and 19F and 29Si n.m.r. spectroscopy.Many have been identified for the first time.
