1433090-69-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1433090-69-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,3,0,9 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1433090-69:
(9*1)+(8*4)+(7*3)+(6*3)+(5*0)+(4*9)+(3*0)+(2*6)+(1*9)=137
137 % 10 = 7
So 1433090-69-7 is a valid CAS Registry Number.

Three-dimensionally arranged cyclic p-hexaphenylbenzene: Toward a bottom-up synthesis of size-defined carbon nanotubes

Nishiuchi, Tomohiko,Feng, Xinliang,Enkelmann, Volker,Wagner, Manfred,Müllen, Klaus

supporting information, p. 16621 - 16625 (2013/03/14)

Go to three dimensions: As a step toward a bottom-up synthesis of size-defined carbon nanotubes (CNTs), [3]cyclo-4′, 4′′′′-hexaphenylbenzenes ([3]CHPBs) were synthesized and investigated. Theoretical and experimental results revealed that [3]CHPBs possess highly twisted [9]cyclo-p-phenylene cores. [3]cyclo-2,11-(Hexa-peri- hexabenzocoronene) ([3]CHBC) was also examined for CNT synthesis (see figure). Copyright
