24922-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24922-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,9,2 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24922-39:
(7*2)+(6*4)+(5*9)+(4*2)+(3*2)+(2*3)+(1*9)=112
112 % 10 = 2
So 24922-39-2 is a valid CAS Registry Number.

Schiff bases derived from 6-amino-2H-chromen-2-one. Synthesis and 1H NMR spectra
Ganushchak,Kobrin,Bilaya,Mizyuk

A number of 6-arylmethylideneamino-2H-chromen-2-ones were synthesized by reaction of 6-amino-2H-chromen-2-one with aromatic and heterocyclic aldehydes. A linear relation was revealed between the chemical shifts of the azomethine CH=N proton and protons in
