Check Digit Verification of cas no

The CAS Registry Mumber 154913-13-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,9,1 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 154913-13:
(8*1)+(7*5)+(6*4)+(5*9)+(4*1)+(3*3)+(2*1)+(1*3)=130
130 % 10 = 0
So 154913-13-0 is a valid CAS Registry Number.

Synthesis and exploratory photophysical investigation of donor-bridge-acceptor systems derived from N-substituted 4-piperidones

Scherer, T.,Hielkema, W.,Krijnen, B.,Hermant, R. M.,Eijckelhoff, C.,et al.

, p. 535 - 548 (2007/10/02)

We report a two-step synthesis for N-aryl- and N-alkyl-substituted 4-piperidones, in which the N substituent can easily be varied.A number of intramolecular donor-acceptor systems was synthesized from these piperidones by conversion of the carbonyl functionality.The influence of the N-aryl donor on the electronic absorption and fluorescence spectra was investigated systematically.It was concluded that some systems can be used as efficient fluorescent probes with a high sensitivity for solvent polarity.
