Check Digit Verification of cas no
The CAS Registry Mumber 13092-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,9 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13092-45:
(7*1)+(6*3)+(5*0)+(4*9)+(3*2)+(2*4)+(1*5)=80
80 % 10 = 0
So 13092-45-0 is a valid CAS Registry Number.

An A6 + B2 approach was applied for the first time to synthesize novel hyperbranched pyridylphenylene polymers by Diels-Alder cyclocondensation reaction. For this, the first-generation pyridylphenylene dendrimer with six ethynyl functionalities (A6) was used as a branching core for the molecule growth. The phenyl-substituted bis(cyclopentadienone)s (B2) of different structures were used as co-monomer in the reaction. A careful choice of reaction conditions allowed us to obtain high molecular weight polymers without undesirable gelation. The molecular weight of the polymers varied in the range of 10800-80100 with a polydispersity degree of 1.69 to 4.07 according to SEC analysis. The 1H and inverse-gated decoupling 13C NMR combined with heteronuclear single quantum correlation and heteronuclear multiple bond correlation measurements were used to estimate the branching degree of the polymers synthesized.

An improved strategy for the synthesis of 3,3′-(oxy-p-phenylene)bis(2,4,5-triphenylcyclopentadienone) was developed, which includes three steps: Friedel-Crafts reaction, oxidation and condensation. Importantly, the use of KMnO4 made the second step simple and efficient, which has potential application to synthesis of bis(cyclopentadienone)s. The course of oxidation has been confirmed by isolated intermediates.
