Check Digit Verification of cas no

The CAS Registry Mumber 204195-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,1,9 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 204195-45:
(8*2)+(7*0)+(6*4)+(5*1)+(4*9)+(3*5)+(2*4)+(1*5)=109
109 % 10 = 9
So 204195-45-9 is a valid CAS Registry Number.

Synthesis and self-assembly of a rigid exotopic bisphenanthroline macrocycle: Surface patterning and a supramolecular nanobasket

Kalsani, Venkateshwarlu,Ammon, Horst,Jaeckel, Frank,Rabe, Juergen P.,Schmittel, Michael

, p. 5481 - 5492 (2004)

The synthesis and characterisation of a rigid nanoscale macrocycle with two exotopic phenanthroline binding sites is reported. Scanning tunnelling microscopy (STM) at the solid-liquid interface reveals the formation of highly ordered monolayers of macrocy
