Check Digit Verification of cas no

The CAS Registry Mumber 1297583-31-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,7,5,8 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1297583-31:
(9*1)+(8*2)+(7*9)+(6*7)+(5*5)+(4*8)+(3*3)+(2*3)+(1*1)=203
203 % 10 = 3
So 1297583-31-3 is a valid CAS Registry Number.

Efficient and straightforward click synthesis of structurally related dendritic triazoles

Mangione,Spanevello,Anzardi

, p. 47681 - 47688 (2017/10/23)

A simple, rapid and efficient copper-catalyzed 1,3-dipolar cycloaddition reaction is described for the synthesis of a novel family of twelve triazolic dendrimers structurally related. The products were the result of the click reaction of three cores and four different azides in tetrahydrofuran applying a homogeneous copper catalysis. The reaction intermediates and products were obtained in very good to excellent yields using straightforward and simple work-up procedures. This new family of compounds contain electroactive moieties such as carbazole and triphenylamine which may turn them into excellent candidates for the development of optoelectronic organic materials.
