Check Digit Verification of cas no

The CAS Registry Mumber 1175050-86-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,5,0,5 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1175050-86:
(9*1)+(8*1)+(7*7)+(6*5)+(5*0)+(4*5)+(3*0)+(2*8)+(1*6)=138
138 % 10 = 8
So 1175050-86-8 is a valid CAS Registry Number.

COMPOUND HAVING SUBSTITUTED PYRIDYL GROUP AND PYRIDOINDOLE RING STRUCTURE LINKED THROUGH PHENYLENE GROUP, AND ORGANIC ELECTROLUMINESCENT DEVICE

-

Page/Page column 43, (2010/11/03)

Objects of the present invention are to provide an organic compound having excellent properties, which is excellent in electron-injecting/transporting performances, has hole-blocking ability and is highly stable in a thin-film state, as a material for an organic electroluminescent device having a high efficiency and a high durability; and to provide an organic electroluminescent device having a high efficiency and a high durability using the compound. The invention relates to a compound having a substituted pyridyl group and a pyridoindole ring structure linked through a phenylene group, which is represented by the general formula (1); and an organic EL device comprising a pair of electrodes and at least one organic layer interposed between the electrodes, wherein the at least one organic layer contains the compound: wherein Ar represents a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; R1 to R14 may be the same or different from each other and each represents a hydrogen atom, a fluorine atom, a chlorine atom, a cyano group, a trifluoromethyl group, a linear or branched alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group; n represents an integer of 1 to 3; and W, X, Y, and Z respectively represent a carbon atom or a nitrogen atom, provided that only one of W, X, Y, and Z represents a nitrogen atom, and the nitrogen atom does not have the substituent of R7, R8, R9, or R10).
