5751-84-8 Usage

General Description

2-Thiophenecarboxylic acid, 5-nitro-, ethyl ester is a chemical compound that belongs to the class of organic compounds known as nitrobenzenes. It is used in industrial processes as a precursor in the production of various chemical compounds. 2-Thiophenecarboxylic acid, 5-nitro-, ethyl ester is synthesized by reacting 5-nitro-2-thiophenecarboxylic acid with ethanol in the presence of a strong acid catalyst. The resulting ethyl ester of 2-thiophenecarboxylic acid with a nitro substituent is a yellow crystalline substance that is commonly used in the synthesis of pharmaceuticals and agrochemicals due to its versatile reactivity and functional groups. Additionally, it serves as an important building block in organic chemistry, with potential applications in the development of new materials and substances.

Check Digit Verification of cas no

The CAS Registry Mumber 5751-84-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,5 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5751-84:
(6*5)+(5*7)+(4*5)+(3*1)+(2*8)+(1*4)=108
108 % 10 = 8
So 5751-84-8 is a valid CAS Registry Number.
