5354-81-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5354-81-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,5 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5354-81:
(6*5)+(5*3)+(4*5)+(3*4)+(2*8)+(1*1)=94
94 % 10 = 4
So 5354-81-4 is a valid CAS Registry Number.

New procedure for obtaining indomethacin

Magedov,Maklakov,Smushkevich

, p. 449 - 451 (2005)

A new procedure has been developed for the synthesis of indomethacin by the Fischer reaction, based on the acylation of sodium 2-(4-methoxyphenyl)-1- hydrazosulfonate with 4-chlorobenzoyl chloride and subsequent interaction with levulinic acid in the presence of formic acid. 2005 Springer Science+Business Media, Inc.

Synthetic Route to Phenyl Diazenes and Pyridazinium Salts from Phenylazosulfonates

Gradl, Susanne,K?ckenberger, Johannes,Oppl, Janina,Schiller, Martin,Heinrich, Markus R.

, p. 6228 - 6238 (2021)

The synthesis of pyridazinium salts was achieved from readily available phenylazosulfonates in a single reaction step. The reaction proceeds via the formation of short-lived phenyldiazenes, which-owing to the strongly acidic conditions-are partially proto
