112906-44-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 112906-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,9,0 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 112906-44:
(8*1)+(7*1)+(6*2)+(5*9)+(4*0)+(3*6)+(2*4)+(1*4)=102
102 % 10 = 2
So 112906-44-2 is a valid CAS Registry Number.

Synthesis and properties of isomerically pure anthrabisbenzothiophenes

Lehnherr, Dan,Hallani, Rawad,McDonald, Robert,Anthony, John E.,Tykwinski, Rik R.

, p. 62 - 65 (2012)

The synthesis of three heptacyclic heteroacenes is described, namely anthra[2,3-b:7,6-b′]bis[1]benzothiophenes (ABBTs). A stepwise sequence of aldol reactions provides regiochemical control, affording only the syn-isomer. The ABBTs are characterized by X-ray crystallography, UV-vis absorption, and emission spectroscopy, as well as cyclic voltammetry. Field effect transistors based on solution-cast thin films of ABBT derivatives exhibit charge-carrier mobilities of as high as 0.013 cm2/(V s).

Selective acceleration for deprotection of benzyl ethers with ti-HMS

Itoh, Akichika,Kodama, Tomohiro,Maeda, Shiro,Masaki, Yukio

, p. 9461 - 9464 (2007/10/03)

Ti-HMS, a Ti-loaded hexagonal mesoporous silica, was found to accelerate deprotection of benzyl ethers under hydrogenolytic conditions with palladium catalyst. Such acid-sensitive functional groups as silyl ether and acetal moieties in the molecule were little affected by Ti-HMS, which possesses Lewis acid sites due to Ti-atom.
