42046-91-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42046-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,4 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42046-91:
(7*4)+(6*2)+(5*0)+(4*4)+(3*6)+(2*9)+(1*1)=93
93 % 10 = 3
So 42046-91-3 is a valid CAS Registry Number.

Synthesis of N-vinylazoles from vinyl acetate without using mercury catalysts

Attaryan,Baltayan,Sagatelyan,Takmazyan, K. Ts.

, p. 2176 - 2178 (2008/09/18)

N-Vinyl-substituted pyrazole, 3(5)-methylpyrazole, imidazole, and 1,2,4-triazole were synthesized by addition of the corresponding azoles to vinyl acetate under conditions of phase-transfer catalysis, followed by pyrolysis of N-(1-acetoxyethyl)azoles thus formed at 350-400°C in the presence of water.

Synthesis of N-vinylpyrazoles

Attarian,Matsoyan,Martirosyan

, p. 452 - 455 (2007/10/03)

A method is proposed for the alkylation of pyrazoles with dichloroethane in water in the presence of the phase-transfer catalyst benzyltriethylammonium chloride (TEBAC). It was shown that dehydrochlorination of the corresponding N-(β-chloroethyl)pyrazoles in water under conditions of phase-transfer catalysis proceeds smoothly with the formation of N-vinylpyrazoles in 80-90% yield. 2005 Springer Science+Business Media, Inc.
