862109-12-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 862109-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,1,0 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 862109-12:
(8*8)+(7*6)+(6*2)+(5*1)+(4*0)+(3*9)+(2*1)+(1*2)=154
154 % 10 = 4
So 862109-12-4 is a valid CAS Registry Number.

Two-photon absorption in V-type chromophores with electron-rich heterocyclevinylene bridges

Li, Qianqian,Zhong, Aoshu,Liu, Haijie,Peng, Ming,Liu, Jun,Pei, Zhiguo,Huang, Zhenli,Qin, Jingui,Li, Zhen

, p. 625 - 630 (2012/02/02)

A series of V-type chromophores with electron-rich heterocyclevinylene bridges have been synthesized via Wittig-Horner-Emmons and Vilsmeier reactions. All the target chromophores showed strong one-photon and two-photon excited emission, and their electron properties could be tuned by using different heterocycles such as furan, thiophene and pyrrole moieties in I-III. The maximum two-photon absorption (TPA) cross sections occurred at 760 nm and were measured to be in the range of 400-800 GM.
