α-Benzylidene-2-carboxybenzofuran-3-acetic acid is a complex organic compound with the molecular formula C18H12O5. It is characterized by a benzofuran core, which is a fused ring system consisting of a benzene ring and a furan ring. The α-benzylidene group indicates the presence of a phenyl group (benzene ring) connected to the benzofuran through an acetylene bridge. The 2-carboxybenzo part of the name suggests that there is a carboxylic acid group attached to the benzene ring at the 2nd position. The 3-acetic acid ending indicates that there is an acetic acid group (a methyl group and a carboxylic acid group) attached to the benzofuran ring at the 3rd position. α-benzylidene-2-carboxybenzofuran-3-acetic acid is likely to be used in the synthesis of pharmaceuticals or other organic compounds due to its unique structure and functional groups.

77117-04-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77117-04-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,1 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77117-04:
(7*7)+(6*7)+(5*1)+(4*1)+(3*7)+(2*0)+(1*4)=125
125 % 10 = 5
So 77117-04-5 is a valid CAS Registry Number.
