175136-47-7 Usage
General Description
2-Ethyl-2,3,4,5-tetrahydro-1,4-benzoxazepine-3,5-dione, also known as etazene, is a chemical compound that belongs to the class of benzoxazepine derivatives. It is a white solid with a molecular formula of C11H11NO3 and a molar mass of 209.21 g/mol. Etazene has been used as a narcotic analgesic drug in some countries, and it is known for its potent opioid effects. However, it has also been associated with a high risk of addiction, abuse, and overdose, leading to its classification as a controlled substance in many jurisdictions. The compound is not approved for medical use in the United States and several other countries due to safety and abuse concerns.
Check Digit Verification of cas no
The CAS Registry Mumber 175136-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,1,3 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 175136-47:
(8*1)+(7*7)+(6*5)+(5*1)+(4*3)+(3*6)+(2*4)+(1*7)=137
137 % 10 = 7
So 175136-47-7 is a valid CAS Registry Number.

2-Alkyl-1,4-benzoxazepin-3,5-diones (8) were readily prepared by cyclodehydration of 2-(o-carbamoilphenoxy)alkanoic acids (7) in acetic anhydride, and with low yields by the same reaction of 2-(o-carboxyphenoxy)alkanoic acid amides (4). The novel acid amides 4 were synthesized from salicylaldehyde and 2-bromo esters 1, via formyl amides 3. The acid amides 7 were formed directly by condensation of salicylamides with 2-bromo esters 1 in dimethyl formamide or by hydrolysis of esters 6 obtained by the same reaction in methyl-ethyl ketone solution.
