Check Digit Verification of cas no
The CAS Registry Mumber 28153-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,5 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 28153-22:
(7*2)+(6*8)+(5*1)+(4*5)+(3*3)+(2*2)+(1*2)=102
102 % 10 = 2
So 28153-22-2 is a valid CAS Registry Number.

Azines or di-imines are compounds containing R1R2C=N-N=CR3R4 fragment in its structure. These compounds have received special attention due to their importance as intermediates in the synthesis of drugs and substances with diverse pharmacological activities. In this research, twelve compounds derived of asymmetric azines of aryl aldehydes and aryl ketones were synthesized by microwave assisted irradiation, and their ability to inhibit acetylcholinesterase (AChE) enzyme was tested using the Ellman method. Among the evaluated azines, five compounds were able to inhibit AChE, especially compounds (7E, 8E)-1-benzylidene-2-(1-(4-nitrophenyl)ethylidene)hydrazine (7) and (7E,8E)-2-(1-(4-nitrophenyl)ethylidene)-1-((pyridin-2-yl)methylene)hydrazine (14), which showed percentage inhibition of 18.34% and 17.43% at concentrations of 22.46 and 10 μM, respectively.

A general and useful method for the synthesis of N-unsubstituted hydrazones of aromatic ketones and aldehydes in good yields was elaborated. The use of a large excess of hydrazine hydrate and catalytic amounts of p-toluenesulfonic acid makes it possible to prepare the hydrazones without an admixture of the corresponding azine.
