Check Digit Verification of cas no

The CAS Registry Mumber 1338213-31-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,2,1 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1338213-31:
(9*1)+(8*3)+(7*3)+(6*8)+(5*2)+(4*1)+(3*3)+(2*3)+(1*1)=132
132 % 10 = 2
So 1338213-31-2 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.
