Check Digit Verification of cas no

The CAS Registry Mumber 147274-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,2,7 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 147274-72:
(8*1)+(7*4)+(6*7)+(5*2)+(4*7)+(3*4)+(2*7)+(1*2)=144
144 % 10 = 4
So 147274-72-4 is a valid CAS Registry Number.

Investigation of different synthetic routes to and structure-property relationships of poly(m-phenylenevinylene-co-2,5-dioctyloxy-p-phenylenevinylene)

Drury, Anna,Maier, Stefanie,Ruether, Manuel,Blau, Werner J.

, p. 485 - 490 (2003)

The synthesis of poly(m-phenylenevinylene-co-2,5-dioctyloxy-p-phenylenevinylene) by Horner-Emmons and Wittig condensation polymerisation in three different solvents is described. The chemical and optical properties of the derivatives thus formed are analy

Synthesis and nonlinear optical properties of rod-like luminescent materials containing Schiff-base and naphthalimide units

Zhang, Yingchao,Zhu, Weihong,Wang, Wenjun,Tian, He,Su, Jianhua,Wang, Wencheng

, p. 1294 - 1300 (2002)

Two series of novel rod-like compounds containing Schiff-base and naphthalimide units were synthesized. The liquid crystalline and amorphous phases of these compounds have been studied by differential scanning calorimetry (DSC), polarizing microscopy and

Stereoretentive Ring-Opening Metathesis Polymerization to Access All- cis Poly(p-phenylenevinylene)s with Living Characteristics

Hsu, Ting-Wei,Kim, Cheoljae,Michaudel, Quentin

, p. 11983 - 11987 (2020/08/06)

Poly(p-phenylenevinylene)s (PPVs), a staple of the conductive polymer family, consist of alternating alkene and phenyl groups in conjugation. The physical properties of this organic material are intimately linked to the cis/trans configuration of the alkene groups. While many synthetic methods afford PPVs with all-trans stereochemistry, very few deliver the all-cis congeners. We report herein a synthesis of all-cis PPVs with living characteristics via stereoretentive ring-opening metathesis polymerization (ROMP). Exquisite catalyst control allows for the preparation of homopolymers or diblock copolymers with perfect stereoselectivity, narrow dispersities, and predictable average molar masses. All-cis PPVs can then serve as light-responsive polymers through clean photoisomerization of the stilbenoid units.

Supramolecular Multiblock Copolymers Featuring Complex Secondary Structures
