Check Digit Verification of cas no

The CAS Registry Mumber 1439383-45-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,3,8 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1439383-45:
(9*1)+(8*4)+(7*3)+(6*9)+(5*3)+(4*8)+(3*3)+(2*4)+(1*5)=185
185 % 10 = 5
So 1439383-45-5 is a valid CAS Registry Number.

Method for synthesizing 5-substituted barbituric acid derivative under catalysis of rare earth chloride

-

Paragraph 0035-0037, (2020/01/03)

The invention belongs to the technical field of synthetic chemistry, and particularly relates to a method for synthesizing a 5-substituted barbituric acid derivative under the catalysis of a rare earth chloride. The preparation method comprises: dissolving a halogenated hydrocarbon and 1,3-dimethyl barbituric acid in an organic solvent, carrying out a reaction for 6-10 h at a room temperature by using a rare earth chloride as a catalyst, and separating and purifying to obtain the 5-substituted barbituric acid derivative. According to the invention, the method has characteristics of simple andenvironmentally-friendly synthesis process, excellent selectivity, high yield and wide substrate range, and further has wide application value in the fields of biology, pharmaceutical chemistry industry and the like.

Functionalization of Csp3-H and Csp 2-H bonds: Synthesis of spiroindenes by enolate-directed ruthenium-catalyzed oxidative annulation of alkynes with 2-aryl-1,3-dicarbonyl compounds

Reddy Chidipudi, Suresh,Khan, Imtiaz,Lam, Hon Wai

, p. 12115 - 12119 (2013/01/16)

Ru(de) awakening: The synthesis of carbocycles by the ruthenium-catalyzed oxidative annulation of alkynes with 2-aryl cyclic 1,3-dicarbonyl substrates is described. Proceeding by the functionalization of C sp 3-H and C sp 2-H bonds, and the formation of an all-carbon quaternary center, the reaction provides a diverse range of spiroindenes in good yields with high levels of regioselectivity.
