General Description
"(3,3'-Bithiophene)-5-carboxaldehyde", sometimes abbreviated as BTCA, is an aromatic, organic compound that contains both the aldehyde and the thiophene functional groups. This chemical agent is primarily used in the synthesis of electronic materials due to its electrical properties, and is a prominent compound in research related to organic electronics, often in the creation of organic thin-film transistors (OTFTs), organic photovoltaics (OPVs), and other molecular electronic devices. Despite its complex name, the chemical is usually just a yellow-to-orange crystalline powder at room temperature. Its systematic (IUPAC) name is 5-(3,3'-bithiophen-5-yl)-2-formylfuran. In terms of warning and hazards, it is noted to cause eye irritation and it is advised to avoid breathing the dust or fume.
Check Digit Verification of cas no
The CAS Registry Mumber 137320-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,2 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137320-59:
(8*1)+(7*3)+(6*7)+(5*3)+(4*2)+(3*0)+(2*5)+(1*9)=113
113 % 10 = 3
So 137320-59-3 is a valid CAS Registry Number.
