Check Digit Verification of cas no

The CAS Registry Mumber 1639839-73-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,9,8,3 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1639839-73:
(9*1)+(8*6)+(7*3)+(6*9)+(5*8)+(4*3)+(3*9)+(2*7)+(1*3)=228
228 % 10 = 8
So 1639839-73-8 is a valid CAS Registry Number.

Improving the reactivity of phenylacetylene macrocycles toward topochemical polymerization by side chains modification

Rondeau-Gagne, Simon,Neabo, Jules Romeo,Daigle, Maxime,Cantin, Katy,Morin, Jean-Francois

, p. 1613 - 1619 (2014)

The synthesis and self-assembly of two new phenylacetylene macrocycle (PAM) organogelators were performed. Polar 2-hydroxyethoxy side chains were incorporated in the inner part of the macrocycles to modify the assembly mode in the gel state. With this modification, it was possible to increase the reactivity of the macrocycles in the xerogel state to form polydiacetylenes (PDAs), leading to a significant enhancement of the polymerization yields. The organogels and the PDAs were characterized using Raman spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM).
