4504-12-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4504-12-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,0 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4504-12:
(6*4)+(5*5)+(4*0)+(3*4)+(2*1)+(1*2)=65
65 % 10 = 5
So 4504-12-5 is a valid CAS Registry Number.

The Chemistry of 5-Oxodihydroisoxazoles. XIV. Synthesis of 2-(1-Aryltetrazol-5-yl)propanoic Acids

Caiazza, Daniela,Prager, Rolf H.,Schafer, Karl

, p. 1861 - 1872 (2007/10/03)

A number of N-arylisoxazol-5(2H)-ones (aryl = phenyl, isoquinolin-1-yl, quinolin-2-yl, 2-phenylquinazolin-4-yl and benzothiazol-2-yl) have been reacted with lithium azide to give 2-(1-aryltetrazol-5-yl)acetic esters, which have been C-methylated and hydrolysed.The resulting 2-(1-aryltetrazol-5-yl)propanoic acid had low antiinflammatory activity, as judged by inhibition of synthesis of prostaglandin PGE2 or tumor necrosis factor α.
