18076-62-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18076-62-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,7 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18076-62:
(7*1)+(6*8)+(5*0)+(4*7)+(3*6)+(2*6)+(1*2)=115
115 % 10 = 5
So 18076-62-5 is a valid CAS Registry Number.

Azobenzene-tethered bis(trityl alcohol) as a photoswitchable cooperative acid catalyst for Morita-Baylis-Hillman reactions

Imahori, Tatsushi,Yamaguchi, Ryo,Kurihara, Seiji

supporting information; experimental part, p. 10802 - 10807 (2012/09/22)

Incorporation of an azobenzene core into tethered bis(trityl alcohol) allows the photoswitchable arrangement of the two trityl alcohol units through photoisomerization of azobenzene. The differently arranged trityl alcohol units change their cooperative function to reflect the positional relationships, and thus, the activity as a cooperative acid can be controlled by light stimuli (see figure).

Acid-catalyzed cyclization reactions of 2,2′ -bis(diarylhydroxymethyl)biphenyls to 5,5,7,7-tetraaryl-5,7-dihydrodibenzo[c,e]oxepins in the solid state

Hirano, Shinya,Toyota, Shinji,Toda, Fumio

, p. 749 - 756 (2007/10/03)

Heating of 2:1 inclusion crystals of 2,2′ -bis(hydroxydiphenylmethyl)biphenyl and formic acid in the solid state gave 5,5,7,7-tetraphenyl-5,7-dihydrodibenzo[c,e]oxepin in 89% yield. When mixtures of 2,2′-bis([bis(p-methoxyphenyl)hydroxymethyl]biphenyl and

Complexation with Diol Host Compounds. Part 10. Synthesis and Solid State Inclusion Properties of Bis(diarylhydroxymethyl)-substituted Benzenes and Biphenyls; X-Ray Crystal Structures of Two Host Polymorphs and of a Non-functional Host Analogue

Weber, Edwin,Skobridis, Konstantinos,Wierig, Andreas,Nassimbeni, Luigi R.,Johnson, Louise

, p. 2123 - 2130 (2007/10/02)

A new family of host molecules where the molecular axis of usual 'wheel-and-axle' compounds is replaced by aromatic units is described.These diol hosts form crystalline inclusions with a variety of uncharged organic molecules mainly of a polar nature (53
