24499-57-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24499-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,4,9 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 24499-57:
(7*2)+(6*4)+(5*4)+(4*9)+(3*9)+(2*5)+(1*7)=138
138 % 10 = 8
So 24499-57-8 is a valid CAS Registry Number.

Reactions of substituted carbohydrazides with electron-poor olefins

Hassan, Alaa A.,Ibrahim, Yusria R.,Shawky, Ahmed M.

experimental part, p. 998 - 1004 (2009/03/11)

Substituted carbohydrazides 1a-e reacted with ethenetetracarbonitrile (2) in dimethylformamide with formation of diacylhydrazines 4a-e and 5-amino-1-substiuted pyrazole-3,3,4-tricarbonitriles 5a-e. On the other hand, 1a-c reacted with diethyl (E)-2,3-dicy

Migration of an acyl group in the pyrazole system: Synthesis of 1-acyl-3-hydroxy-1H-pyrazoles and related derivatives. A new preparation of N,N′-diacylhydrazines

Kepe, Vladimir,Pozgan, Franc,Golobic, Amalija,Polanc, Slovenko,Kocevar, Marijan

, p. 2813 - 2816 (2007/10/03)

A new general method for the synthesis of 1-acyl-3-hydroxy-1H-pyrazoles 5a-f and related derivatives 5g-i starting from 4-ethoxymethylene-2-phenyloxazol-5(4H)-one (1) and hydrazides, 4-phenylsemicarbazide, 4-phenylthiosemicarbazide and benzyl carbazate in boiling dioxane is described. The method includes a migration of an acyl or related unit. The X-ray study and NMR spectroscopic examination confirmed the structure of the products. A one-pot synthesis of N,N′-diacylhydrazines from hydrazides by the assistance of oxazolone 1 is also presented.
