39145-31-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39145-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,1,4 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39145-31:
(7*3)+(6*9)+(5*1)+(4*4)+(3*5)+(2*3)+(1*1)=118
118 % 10 = 8
So 39145-31-8 is a valid CAS Registry Number.

Multicomponent Synthesis and Molecular and Crystal Structure of New Derivatives of Partially Hydrogenated Quinolines

Dorovatovskii, P. V.,Dyachenko, I. V.,Dyachenko, V. D.,Khrustalev, V. N.,Nenaidenko, V. G.

, p. 1824 - 1833 (2021/12/22)

Abstract: The multicomponent condensation of aromatic aldehydes, cyanothioacetamide, 1-(cyclohex-1-en-1-yl)azepine, and α-halocarbonyl compounds was studied. As a result, new derivatives of partially hydrogenated quinolines were synthesized. The molecular and crystal structures of a number of the synthesized heterocycles were studied X-ray analysis.

Design and synthesis of pyrido[2,1- b ][1,3,5]thiadiazine library via uncatalyzed mannich-type reaction

Dotsenko, Victor V.,Frolov, Konstantin A.,Pekhtereva, Tatyana M.,Papaianina, Olena S.,Suykov, Sergey Yu.,Krivokolysko, Sergey G.

, p. 543 - 550 (2014/12/10)

This Research Article describes the synthesis of an over 700-member library of (8R/8S)-3-R-8-aryl-6-oxo-3,4,7,8-tetrahydro-2H,6H-pyrido[2,1-b][1,3,5]thiadiazin-9-carbonitriles by uncatalyzed Mannich-type reaction of N-methylmorpholinium (4R/4S)-4-aryl-3-cyano-6-oxo-1,4,5,6-tetrahydropyridin-2-thiolates with a set of primary amines and excessive HCHO. The scope and limitations of the reaction were studied. Starting thiolates were obtained in yields of 53-82% by multicomponent reaction of aromatic aldehydes, cyanothioacetamide, 2,2-dimethyl-1,3-dioxane-4,6-dione (Meldrum's acid), and N-methylmorpholine, followed by heterocyclization of the resulting Michael adducts.

The behaviour of arylidenemalononitriles towards certain thiating phosphorus reagents

Abd El-Rahman, Naglaa M.

, p. 465 - 468 (2007/10/03)

The behaviour of arylidenemalononitriles 1, 2 and 3 towards certain thiating phosphorus reagents, namely, phosphorus pentasulfide and Lawesson's reagent 10, has been outlined. The products obtained depend on the nature of reactants. Analytical and spectro
