1268840-14-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1268840-14-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,8,4 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1268840-14:
(9*1)+(8*2)+(7*6)+(6*8)+(5*8)+(4*4)+(3*0)+(2*1)+(1*4)=177
177 % 10 = 7
So 1268840-14-7 is a valid CAS Registry Number.

1H-benzo[g]indole compounds and organic luminescence device using the same

-

Page/Page column 30, (2011/04/18)

Embodiments of the present Invention are directed to heteroarylamine compounds wherein: each of Ar1 and Ar2 is independently selected from the group consisting of substituted and unsubstituted C6-C60 aryl groups, substituted and unsubstituted C4-C60 heteroaryl groups, and substituted and unsubstituted C6-C60 condensed polycyclic groups; X1 is selected from the group consisting of substituted and unsubstituted C6-C30 arylene groups, substituted and unsubstituted C4-C30 heteroarylene groups, and substituted and unsubstituted C6-C30 condensed polycyclic groups; and organic luminescence devices including the heteroarylamine compounds. The organic luminescence devices using the heteroarylamine compounds have high-efficiency, low driving voltages, high luminance and long lifetimes.
