128371-17-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128371-17-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,7 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128371-17:
(8*1)+(7*2)+(6*8)+(5*3)+(4*7)+(3*1)+(2*1)+(1*7)=125
125 % 10 = 5
So 128371-17-5 is a valid CAS Registry Number.

A novel one-pot synthesis of substituted pyridazines: A general method of preparation of 3,4,6-tri aryl pyridazines

Nongkhlaw, Rishan Lang,Nongrum, Ridaphun,Myrboh, Bekington

, p. 465 - 472 (2007/10/03)

3,4,6-triaryl pyridazines 4 were conveniently prepared in one step by the condensation of aryl methyl ketones and 1,2-diketones in presence of base, followed by cyclisation with hydrazines.

Organophosphorus Chemistry, XII. Reaction of Furil with Alkyl Phosphites and Ylide-Phosphoranes

Mahran, Mohamed R.,Abdou, Wafaa M.,Khidre, Maha D.

, p. 51 - 58 (2007/10/02)

The reaction of furil (1) with trialkyl phosphites 2 yielded caged phosphorane derivatives of types 3 a-c.Dry hydrogen chloride gas converted 3 a-c into the respective α-hydroxyvinyl-phosphates 8 a-c which are equally produced by reacting furil with the appropriate dialkyl phosphite 7.The reaction of furil with ylide-phosphoranes 10 proceeded according to the Wittig reaction mechanism to give the respective ethylenes 11 a-c.The new compounds have been characterized by their spectroscopic data (IR, PMR, 31P-NMR, MS) and elementary analyses.
