5-(7-bromobenzo[c][1,2,5]thiadiazol-4-yl)thiophene-2-carbaldehyde is a complex organic compound characterized by its unique molecular structure. It features a thiophene ring, which is a five-membered aromatic ring containing one sulfur atom, and a benzo[c][1,2,5]thiadiazole ring, which is a fused ring system consisting of a benzene ring attached to a [1,2,5]thiadiazole ring. The presence of a bromine atom at the 7-position of the benzo[c][1,2,5]thiadiazole ring and an aldehyde group at the 2-position of the thiophene ring further distinguish 5-(7-bromobenzo[c] [1,2,5] thiadiazol-4-yl) thiophene-2-carbaldehyde. This chemical is significant in the field of organic synthesis and material science, potentially serving as a building block for the development of new pharmaceuticals, agrochemicals, or advanced materials due to its diverse functional groups and aromatic character.

Check Digit Verification of cas no

The CAS Registry Mumber 1309922-61-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,9,2 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1309922-61:
(9*1)+(8*3)+(7*0)+(6*9)+(5*9)+(4*2)+(3*2)+(2*6)+(1*1)=159
159 % 10 = 9
So 1309922-61-9 is a valid CAS Registry Number.

Dissymmetrization of Benzothiadiazole by Direct C–H Arylation: A Way to Symmetrical and Unsymmetrical Elongated π-Conjugated Molecules

supporting information, p. 6872 - 6877 (2017/12/26)

5-(7-Bromo-2,1,3-benzothiadiazol-4-yl)-2-thiophenecarbaldehyde is a small building block of great interest for its use in the elaboration of symmetrical or unsymmetrical donor–acceptor π-conjugated molecules for optoelectronic applications. Herein, a convenient, one-pot, two-component synthesis of this intermediate is reported, based upon a palladium-catalysed, phosphine- and additive-free, direct C–H arylation process. The synthesis has been studied in depth to obtain optimum yields and selectivity by an efficient and environmentally friendly strategy for sustainable synthesis.
