Check Digit Verification of cas no

The CAS Registry Mumber 1449415-35-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,4,1 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1449415-35:
(9*1)+(8*4)+(7*4)+(6*9)+(5*4)+(4*1)+(3*5)+(2*3)+(1*5)=173
173 % 10 = 3
So 1449415-35-3 is a valid CAS Registry Number.

Further enhancement of the second-order nonlinear optical (NLO) coefficient and the stability of NLO polymers that contain isolation chromophore moieties by using the suitable isolation group concept and the Ar/Ar F self-assembly effect

Wu, Wenbo,Ye, Cheng,Qin, Jingui,Li, Zhen

, p. 1836 - 1846 (2013/09/02)

For the first time, a series of second-order NLO poly(arylene-ethynylene)s, in which an isolation chromophore was introduced to enhance the NLO coefficients, were successfully designed and synthesized. Thanks to the isolation chromophore, these polymers demonstrated good NLO activities and optical transparency. To further improve the comprehensive performance of the polymers, different isolation groups of various sizes were introduced to subtly modify the structure of the polymers according to the suitable isolation group concept. The naphthalene (Np) group was found to be a suitable isolation group in this series of polymers and polymer P3 demonstrated the highest d33 value (122.1 pm V-1) of these five polymers. Interestingly, polymer P5, which contained a pentafluorophenyl ring as an isolation group, exhibited a much higher NLO effect and stability than polymer P2, which just contained normal phenyl rings as isolation groups (97.2 versus 62.5 pm V-1), thus indicating the advantages of the Ar-Ar F self-assembly effect in the field of non-linear optics. Second the best: Second-order NLO poly(arylene-ethynylene)s that contained an isolation chromophore were obtained, in which the isolation groups were introduced by using the suitable isolation group concept or the Ar-ArF self-assembly effect.
