31408-23-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31408-23-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,0 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 31408-23:
(7*3)+(6*1)+(5*4)+(4*0)+(3*8)+(2*2)+(1*3)=78
78 % 10 = 8
So 31408-23-8 is a valid CAS Registry Number.

Probing the Scope of the Amidine–1,2,3-triazine Cycloaddition as a Prospective Click Ligation Method

supporting information, p. 5081 - 5085 (2018/10/20)

Despite recent achievements in the development of chemical reactions enabling selective modification of complex biomolecules, the demand for fast and efficient methodologies that allow the attachment of various functional groups to these systems is the subject of intense research. Here, we report on the study of the amidine–1,2,3-triazine cycloaddition reaction, which has the potential to address many of the challenges associated with the development of such chemistry. We describe an optimized protocol leading to the in situ formation of free amidine bases, which directly react in the cycloaddition reaction with 1,2,3-triazines. Our kinetic studies reveal the structural features determining the reaction rates. Finally, we show that the amidine–1,2,3-triazine cycloaddition is extraordinarily selective and orthogonal to other popular ligation reactions. The pros and cons of the methodology are presented.

The Dimroth rearrangement as a probable cause for structural misassignments in imidazo[1,2-a]pyrimidines: A 15N-labelling study and an easy method for the determination of regiochemistry

Chatzopoulou, Maria,Martínez, R. Fernando,Willis, Nicky J.,Claridge, Timothy D.W.,Wilson, Francis X.,Wynne, Graham M.,Davies, Stephen G.,Russell, Angela J.

, p. 5280 - 5288 (2018/07/21)

Structural misassignments are often seen for complex natural products, but this can also be an issue with seemingly simpler structures. In this paper, we describe how, using a 15N-labelled analogue, we established that the Dimroth rearrangement
