Check Digit Verification of cas no

The CAS Registry Mumber 203579-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,5,7 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203579-40:
(8*2)+(7*0)+(6*3)+(5*5)+(4*7)+(3*9)+(2*4)+(1*0)=122
122 % 10 = 2
So 203579-40-2 is a valid CAS Registry Number.

Synthesis of oligo(phenylene ethynylene)s with dendrimer "shells" for molecular electronics

Shi, Zi-Fa,Wang, Le-Jia,Wang, Hong,Cao, Xiao-Ping,Zhang, Hao-Li

, p. 595 - 598 (2008/02/02)

Two series of oligo(phenylene ethynylene)s (OPEs) with different dendrimer side groups have been designed and synthesized. The molecules contain thiol groups at both ends to enable interconnection between nanoscale gapped metallic electrodes. The different dendrimer groups act as "shells", allowing tailoring to the nanoscopic environment surrounding the OPE "core". Meanwhile, the dendrimer shells also act as spacers for the precise control of the packing density and intermolecular interaction between the OPE cores.
