Check Digit Verification of cas no

The CAS Registry Mumber 18870-11-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,7 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18870-11:
(7*1)+(6*8)+(5*8)+(4*7)+(3*0)+(2*1)+(1*1)=126
126 % 10 = 6
So 18870-11-6 is a valid CAS Registry Number.

Gl?cklhofer, Florian,Lunzer, Markus,St?ger, Berthold,Fr?hlich, Johannes

supporting information, p. 5173 - 5180 (2016/04/09)

A generally applicable direct synthesis of cyanoarenes from quinones is presented. Particular emphasis is placed on the preparation of precursors and target molecules relevant for organic materials, including halogenated cyanoarenes and larger cyanated acenes. The reaction and work-up protocols are adjusted for the challenges presented by the different substrates and products. Screening results of the initial reaction optimization are given to further facilitate adaptation to other synthetic problems. The universality of the reaction is finally highlighted by successful substitution of para-quinones by an ortho-quinone as the starting material.

Synthesis and structure/property correlation of fully functionalized photorefractive polymers

You, Wei,Wang, Liming,Wang, Qing,Yu, Luping

, p. 4636 - 4645 (2007/10/03)

This paper describes the synthesis and physical study of several new photorefractive polymers. The Heck reaction was successfully applied in the synthesis of these multifunctional polymers. These polymers are conjugated poly(phenylenevinylene)s copolymerized with a small amount of macrocyclic zinc complexes as the photosensitizers. Nonlinear optical chromophores were incorporated as the pendant groups. Both electron-rich and electron-deficient PPV backbones were synthesized. Experimental results showed that when an electron-rich photosensitizer is used, the electron-deficient component for charge transport (CN-PPV) enhances photorefractive performance and reduces the response time.
