153862-99-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 153862-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,8,6 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 153862-99:
(8*1)+(7*5)+(6*3)+(5*8)+(4*6)+(3*2)+(2*9)+(1*9)=158
158 % 10 = 8
So 153862-99-8 is a valid CAS Registry Number.

Synthesis, characterization and analgesic activity of new 4-arylhydrazono-3-methoxymethyl-2-pyrazolin-5-ones

Ergenc,Capan,Demirdamar

, p. 118 - 124 (2007/10/03)

New 4-arylhydrazono-3-methoxymethyl-2-pyrazolin-5-ones (5a-j) and 4-arylhydrazono-3-methoxymethyl-1-phenyl-2-pyrazolin-5-ones (6a-j) were synthesized by the reaction of ten novel methyl 2-arylhydrazono-4-methoxy-3-oxobutanoates (4a-j) with hydrazine hydrate and phenylhydrazine, respectively. Treatment of 5a with acetic anhydride yielded 1-acetyl-4-arylhydrazono-3-methoxymethyl-2-pyrazolin-5-one (7). The structures of the tautomerically dynamic compounds were established by spectral data (1R, 1H-NMR, 13C-NMR, EIMS and CIMS) and elemental analysis. The analgesic activity of the title compounds was determined by the modified Koster's test. The most active compound was 4-[(4-chlorophenyl)hydrazono]-3-methoxymethyl-1-phenyl-2-pyrazolin-5-one (6c) demonstrating twice the activity (60 %) exerted by the reference drug acetylsalicylic acid (ASA, 27 %). The majority of the tested compounds were found to be more effective than ASA.
