210905-25-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 210905-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,9,0 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 210905-25:
(8*2)+(7*1)+(6*0)+(5*9)+(4*0)+(3*5)+(2*2)+(1*5)=92
92 % 10 = 2
So 210905-25-2 is a valid CAS Registry Number.

Synthesis and optoelectronic properties of janus -dendrimer-type multivalent donor-acceptor systems

Dengiz, Cagatay,Breiten, Benjamin,Gisselbrecht, Jean-Paul,Boudon, Corinne,Trapp, Nils,Schweizer, W. Bernd,Diederich, Fran?ois

, p. 882 - 896 (2015/01/30)

A convergent, multistep protocol was employed for the synthesis of a Janus-type multivalent donor-acceptor system. The synthetic approach is based on a Sonogashira cross-coupling of two differently ferrocene-(Fc) substituted dendrons and a final sixfold [

Conjugated oligoyne-bridged [60]fullerene molecular dumbbells: Syntheses and thermal and morphological properties

Zhou, Ningzhang,Zhao, Yuming

experimental part, p. 1498 - 1516 (2010/05/02)

Chemical Equation Presented A series of linear and star-shaped π-conjugated oligomer hybrids (2-5) composed of an oligoyne core, ranging from 1,3-butadiyne to 1,3,5,7,9,11-dodecahexayne, and fullerenyl end-capping groups has been synthesized and studied.

Modular Synthesis of Benzene-Centered Porphyrin Trimers and a Dendritic Porphyrin Hexamer

Mongin, Olivier,Papamicael, Cyril,Hoyler, Nicolas,Gossauer, Albert

, p. 5568 - 5580 (2007/10/03)

Rigid, star-shaped D3-symmetric arrays have been synthesized in which three porphyrin macrocyeles are attached to the 1,3, and 5 positions each of a benzene core through linkers consisting of collinear repetitive phenylethynyl units. Using the
