Check Digit Verification of cas no

The CAS Registry Mumber 1247053-53-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,7,0,5 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1247053-53:
(9*1)+(8*2)+(7*4)+(6*7)+(5*0)+(4*5)+(3*3)+(2*5)+(1*3)=137
137 % 10 = 7
So 1247053-53-7 is a valid CAS Registry Number.

MATERIAL FOR USE IN PHOSPHORESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME

-

, (2012/02/15)

Provided is an organic electroluminescent device (organic EL device), in which the luminous efficiency of the device is improved, driving stability is sufficiently ensured, and the construction of the device is simple. This organic EL device is an organic electroluminescent device, including a light-emitting layer between an anode and a cathode laminated on a substrate, in which the light-emitting layer contains a phosphorescent light-emitting dopant and an indolocarbazole compound as a host material. Examples of the indolocarbazole compound include a compound represented by the following formula (1). It should be noted that in the formulae: a ring A and a ring B are represented by the formulae (1a) and (1b), respectively; Ar's each represent an aromatic hydrocarbon group or an aromatic heterocyclic group; R's each represent a hydrogen atom, an alkyl group, or a cycloalkyl group; X represents a methine group or a nitrogen atom; A represents an aromatic hydrocarbon group, an alkyl group, a cycloalkyl group, or a group represented by the formula (1c); and n represents 0 or 1.
