General Description
Benzo[b]thiophene-3-acetic acid is a chemical compound characterized by a fusion of benzene, thiophene and acetic acid functional groups. It represents a benzo thiophene derivative, which is essentially a bi-cyclic compound containing a benzene and a thiophene ring fused together. The acetic acid component denotes a carboxylic acid moiety. This chemical is often used in fields such as chemistry and biochemistry research, usually acting as the core structure for the synthesis in the process of creating more complex chemical compounds. Its specific properties and interaction with other compounds may vary based on its configuration and the context in which it is used.
Check Digit Verification of cas no
The CAS Registry Mumber 1131-09-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1131-09:
(6*1)+(5*1)+(4*3)+(3*1)+(2*0)+(1*9)=35
35 % 10 = 5
So 1131-09-5 is a valid CAS Registry Number.

The first ruthenium-catalyzed umpolung carboxylation of hydrazones with CO2 to generate important aryl acetic acids is reported. Besides aldehyde hydrazones, a variety of ketone hydrazones, which have not been successfully applied in previous umpolung reactions with other reactive electrophiles, also show high reactivity and selectivity under mild conditions. Moreover, this operationally simple protocol features good functional group tolerance, is readily scalable, and offers easy derivation of important structures, including bioactive felbinac and adiphenine. Computational studies reveal that this umpolung reaction proceeds through the generation of a Ru-nitrenoid followed by concerted [4 + 2] cycloaddition with CO2.
