942612-13-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 942612-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,2,6,1 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 942612-13:
(8*9)+(7*4)+(6*2)+(5*6)+(4*1)+(3*2)+(2*1)+(1*3)=157
157 % 10 = 7
So 942612-13-7 is a valid CAS Registry Number.

Effects of substitution on the optoelectronic properties of photochromic diarylethenes bearing a pyrrole moiety

Liu, Gang,Pu, Shouzhi,Wang, Xiaomei,Liu, Weijun,Yang, Tianshe

experimental part, p. 71 - 81 (2011/12/01)

Five diarylethenes bearing a pyrrole moiety were synthesized in order to investigate the effects of the substituents on the properties of these compounds. The structures of three of the diarylethenes were determined by single-crystal X-ray diffraction ana

Efficient synthesis and properties of isomeric photochromic diarylethenes having a pyrrole unit

Pu, Shouzhi,Liu, Gang,Shen, Liang,Xu, Jingkun

, p. 2139 - 2142 (2008/02/03)

Two new isomeric photochromic diarylethenes with a pyrrole unit have been developed. Their properties, including photochromic behavior, crystal structures, and fluorescent properties, have been investigated. The two isomeric compounds show distinctly different photochromism, both in solution and in the single-crystalline phase: one turns red upon photocyclization whereas the other turns blue, which may be attributed to the different substituent effects.
