Check Digit Verification of cas no

The CAS Registry Mumber 20322-87-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,2 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20322-87:
(7*2)+(6*0)+(5*3)+(4*2)+(3*2)+(2*8)+(1*7)=66
66 % 10 = 6
So 20322-87-6 is a valid CAS Registry Number.

Using functionalized nonlinear optical chromophores to prepare NLO-active polycarbonate films

González-Lainez,Jiménez-Ruiz,Martínez De Baroja,Garín,Orduna,Villacampa,Blesa

, p. 30 - 40 (2015)

Novel functionalized second order nonlinear optical (NLO) chromophores have been prepared with functionalized aniline as electron donor, thiophene or isophorone as a π-spacer and 1,3-diethyl-2-thiobarbituric acid as electron acceptor. The films prepared from dyes with alkylsilyl bulky groups gave better performance than the corresponding non functionalized chromophores due to the reduction of the intermolecular electrostatic interactions. The incorporation of chromophores 4 and 10 in a polycarbonate matrix allowed the preparation of good optical-quality films. Nonlinear coefficients d33 and d31 as high as 17 and 5.6 pm V-1, respectively, were obtained. Moreover, the temporal stability of these host-guest films was confirmed up to eight months (>80%).
