131755-24-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131755-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,5 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 131755-24:
(8*1)+(7*3)+(6*1)+(5*7)+(4*5)+(3*5)+(2*2)+(1*4)=113
113 % 10 = 3
So 131755-24-3 is a valid CAS Registry Number.

Preparation and Nonlinear Optical Property of Polydiacetylenes from Dialkyltetraacetylene Compounds

Okada, S.,Matsuda, H.,Nakanishi, H.,Kato, M.

, p. 57 - 63 (2007/10/02)

To obtain polydiacetylenes with ?-conjugation between polymer backbone and side chains, diacetylene monomers with acetylenic substituents, i.e., dialkyltetraacetylene compounds, were synthesized.It has been found that they were highly polymerizable on UV or γ-ray irradiation and became deeply blue-colored polymers.It was confirmed that the polymerization proceed topochemically via 1,4-addition to give polydiacetylenes with acetylenic substituents.Third order nonlinear optical susceptibility of these polymers, evaluated from third harmonic generation by Maker fringe method, were larger than that of the corresponding dialkyldiacetylene polymer.
