188185-74-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188185-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,1,8 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 188185-74:
(8*1)+(7*8)+(6*8)+(5*1)+(4*8)+(3*5)+(2*7)+(1*4)=182
182 % 10 = 2
So 188185-74-2 is a valid CAS Registry Number.

Z-isomers of azobenzenes highly compatible with liquid crystals

Ruslim, Christian,Ichimura, Kunihiro

, p. 789 - 790 (1998)

Novel guest-host liquid crystal systems containing 3,3-disubstituted azobenzenes as guests were prepared on the basis of molecular design by molecular calculations to achieve the improvement of compatibility of the chromophore with nematic phases. No phase change of nematic liquid crystals was induced by the E-to-Z photoisomerization of the guests even at doped concentrations as high as 20 wt%.

Total syntheses of the slime mold alkaloid arcyriacyanin A

Brenner, Michael,Mayer, Guido,Terpin, Andreas,Steglich, Wolfgang

, p. 70 - 74 (2007/10/03)

Arcyriacyanin A (1) has been synthesized by three different routes. In the first synthesis the bisbromomagnesium salt of 2,4'-biindole (5) was treated with dibromomaleimide (6) to yield arcyriacyanin A (1). The second approach used an intramolecular Hock
