5045-33-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5045-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,4 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5045-33:
(6*5)+(5*0)+(4*4)+(3*5)+(2*3)+(1*3)=70
70 % 10 = 0
So 5045-33-0 is a valid CAS Registry Number.

Eine einfache Methode zur Herstellung von Benzoxazolen

Seha, Zdenek,Weis, Claus D

, p. 413 - 419 (2007/10/02)

The preparation of benzoxazoles by a facile one-pot reaction is reported.The reaction of carboxylic acids with 2-chloro-N-methyl-Δ1-pyrrolinium chloride in an excess of N-methyl-2-pyrrolidone afforded carboxylic acid chlorides which were converted subsequently to their 2-hydroxyanilides by addition of 2-aminophenols.Cyclization of the 2-hydroxy-anilides at elevated temperatures furnished the benzoxazoles in high yield and purity.
