Check Digit Verification of cas no

The CAS Registry Mumber 121511-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,1 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121511-54:
(8*1)+(7*2)+(6*1)+(5*5)+(4*1)+(3*1)+(2*5)+(1*4)=74
74 % 10 = 4
So 121511-54-4 is a valid CAS Registry Number.

Synthesis, Structure, and Properties of Triple-Layered Naphthalenophane

, p. 164 - 170 (2007/10/02)

The title compound was synthesized in a similar manner to a simple access to triple-layered paracyclophane.Its structure was elucidated by X-ray crystallographic analysis.The outer naphthalene rings are bent into a boat form and the inner naphthalene ring is bent into a twist form.These naphthalenes are stacked in layers within van der Waals contact.Therefore, there is a strong transannular ?-electronic interaction between them, which brings about characteristic bathochromism, hyperchromism, and broadening in the electronic spectrum.These effects are more prominent than those of the double-layered homologue.
