General Description
4-Phenylthiophene-2-Carboxylic Acid is an organic compound consisting of a thiophene moiety substituted at the 2-position by a carboxylic acid function and at the 4-position by a phenyl group. Its molecular formula is C12H10O2S. This chemical has an aromatic ring exhibiting delocalized pi electron systems, making it stable and inert to many chemical reactions. Despite its stability, however, it can undergo reactions under certain conditions, which entail the addition or substitution at its reactive sites. Typically, this chemical is used as a chemical intermediate or a building block during the synthesis of various other compounds, including pharmaceuticals. However, like many chemicals, it can potentially affect human health and the environment if mishandled, making it necessary to handle it with utmost care and in compliance with standard safety procedures. Regular safety evaluation and valid certifications are also required for its manufacturing and usage.
Check Digit Verification of cas no
The CAS Registry Mumber 21676-88-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,7 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21676-88:
(7*2)+(6*1)+(5*6)+(4*7)+(3*6)+(2*8)+(1*8)=120
120 % 10 = 0
So 21676-88-0 is a valid CAS Registry Number.
