General Description
2,3-Dichloroanthracene is a chemical compound that consists of a tricyclic aromatic structure with two chlorine atoms attached at the 2 and 3 position of the anthracene ring system. It is a white to light yellow crystalline solid with a melting point of around 150°C. 2,3-Dichloroanthracene is a polycyclic aromatic hydrocarbon, and like other aromatic compounds, it is relatively stable and exhibits strong resonance stabilization. 2,3-Dichloroanthracene is primarily used as a building block in the synthesis of various organic compounds, including pharmaceuticals, dyes, and pigments. It is also used as a starting material in the preparation of organic semiconductors and in polymer chemistry. 2,3-Dichloroanthracene is considered to be a hazardous chemical and should be handled and disposed of with proper safety precautions.
Check Digit Verification of cas no
The CAS Registry Mumber 613-07-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 613-07:
(5*6)+(4*1)+(3*3)+(2*0)+(1*7)=50
50 % 10 = 0
So 613-07-0 is a valid CAS Registry Number.

2,3-Dihalo- and 2,3,6,7-Tetrahaloanthracenes by Vollhardt Trimerization

We efficiently synthesized otherwise difficult to obtain 2,3- and 2,3,6,7-halogenated anthracenes with diverse east/west substituents. Key steps involve the (i) Vollhardt cyclization of bis(propargyl)benzenes with bis(trimethylsilyl)acetylene, (ii) halo-desilylation introducing chlorine, bromine, or iodine substituents, and (iii) dehydrogenation. Pd catalysis allows selective functionalization at the anthracenes' east/west positions. A tetrahydropentacene is synthesized and derivatized via the same strategy, employing tetrapropargylbenzene.
