Check Digit Verification of cas no
The CAS Registry Mumber 1872-40-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,7 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1872-40:
(6*1)+(5*8)+(4*7)+(3*2)+(2*4)+(1*0)=88
88 % 10 = 8
So 1872-40-8 is a valid CAS Registry Number.

A route to the synthesis of novel 5,7-diazapentacenes and some preliminary studies on their properties is reported. A single crystal X-ray diffraction study of the dihexyl derivative showed it had formed a dimer during the analysis. The materials possess lower lying frontier orbitals than pentacene and may have potential applications in organic electronic devices. This synthetic method may be applicable to the synthesis of other azaacenes.
