31590-01-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31590-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,9 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31590-01:
(7*3)+(6*1)+(5*5)+(4*9)+(3*0)+(2*0)+(1*1)=89
89 % 10 = 9
So 31590-01-9 is a valid CAS Registry Number.

Synthesis and antimicrobial activity of some new triazino-, triazolo-, and pyrazolopyridazine derivatives

Yassin

body text, p. 997 - 1003 (2010/04/03)

The reaction of 3-hydrazino-4,5,6-triphenylpyridazine with phenacyl bromide afforded triazolopyridazine, while the reaction with different aldehydes gave the corresponding 3-arylidene hydrazinopyridazine derivatives which, on reaction with Br2/

Reactions of Grignard Reagents with 4-Cyano-5,6-diphenyl and -6-p-Tolyl-3(2H)-pyridazinones and 6-p-Tolyl-3(2H)-pyridazinethione

Jahine, H.,Zaher, H. A.,Sherif, O.,Seada, M.

, p. 502 - 503 (2007/10/02)

4-Cyano-5,6-diphenyl-3(2H)-pyridazinone (I) reacts with phenylmagnesium bromide to give 4-benzoyl-4,5,6-triphenyl-4,5-dihydro-3(2H)-pyridazinone (II) and 4,5,6-triphenyl-3(2H)-pyridazinone (III).Reaction of 6-p-tolyl-3(2H)-pyridazinone (IV) with phenylmagnesium bromide in THF-ether gives 5-phenyl-6-p-tolyl-4,5-dihydro-3(2H)-pyridazinone (V) and with arylmagnesium bromides in benzene affords 4-aryl-6-tolyl-3(2H)-pyridazinones (IVb-d). 6-p-Tolyl-3(2H)-pyridazinethione (VIa) reacts with arylmagnesium bromides in benzene or THF-ether to give 4-aryl-6-p-tolyl-3(2H)-pyridazinethiones (VIb,c).
