Check Digit Verification of cas no

The CAS Registry Mumber 929117-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,9,1,1 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 929117-67:
(8*9)+(7*2)+(6*9)+(5*1)+(4*1)+(3*7)+(2*6)+(1*7)=189
189 % 10 = 9
So 929117-67-9 is a valid CAS Registry Number.

AZAAROMATIC COMPOUNDS HAVING AZAFLUORANTHENE SKELETONS AND ORGANIC ELECTROLUMINESCENT DEVICES MADE BY USING THE SAME

-

Page/Page column 35-36, (2008/06/13)

The invention aims at providing a novel azaaromatic compound having an azafluoranthene skeleton which is useful as the constituent of organic EL devices and at realizing a long-life, high-efficiency and practical organic EL device by using the compound in at least one of the organic compound layers. The invention provides azaaromatic compounds having azafluo- ranthene skeletons as represented by the general formula (1): wherein R1 to R12 are each independently hydrogen, substituted or unsubstituted alkyl having 1 to 30 carbon atoms, substituted or unsubstituted alkoxy having 1 to 30 carbon atoms, substituted or unsubstituted aryl having 6 to 40 carbon atoms, trialkylsilyl (wherein each alkyl has 1 to 20 carbon atoms and may be substituted), aryloxy (wherein the aryl has 6 to 40 carbon atoms and may be substituted), halogeno, or cyano, with the proviso that at least two of R1 to R12 are each cyano, trifluoromethyl, or fluoro and adjacent two of R1 to R12 may be united to form a ring structure.
