13573-34-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13573-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,7 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13573-34:
(7*1)+(6*3)+(5*5)+(4*7)+(3*3)+(2*3)+(1*4)=97
97 % 10 = 7
So 13573-34-7 is a valid CAS Registry Number.

Direct synthesis of 2,4,5-trisubstituted imidazoles and di/tri-substituted pyrimidines via cycloadditions of α,β-unsaturated ketones/aldehydes and N′-hydroxyl imidamides

Wu, Ping,Zhang, Xueguo,Chen, Baohua

, p. 1103 - 1107 (2019)

An efficient route for the synthesis of 5-acetylimidazoles and di/trisubstituted pyrimidines via iron-catalyzed cross-dehydrogenative coupling (CDC), with excellent tolerance and yields, has been developed. In this report, α,β-unsaturated aldehydes/ketones and N′-hydroxyl imidamides undergo [3+2] and [3+3] cycloadditions in two processes, involving iron-mediated Michael reaction, Robinson Annulation and 1,5-electrocyclization.

Secondary amines immobilized inside magnetic mesoporous materials as a recyclable basic and oxidative heterogeneous nanocatalyst for the synthesis of trisubstituted pyrimidine derivatives

Aryan, Reza,Beyzaei, Hamid,Nojavan, Masoomeh,Dianatipour, Tahereh

, p. 4417 - 4431 (2016/07/06)

A novel magnetic MCM-41 nanocomposite-based catalyst is reported for the first time in the multicomponent synthesis of trisubstituted pyrimidines in which piperazine is immobilized inside the mesochannels of magnetic MCM-41 as an organic base (α-Fe2
