75227-44-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75227-44-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,2 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75227-44:
(7*7)+(6*5)+(5*2)+(4*2)+(3*7)+(2*4)+(1*4)=130
130 % 10 = 0
So 75227-44-0 is a valid CAS Registry Number.

Agrawal, Nitin N.,Soni
, p. 532 - 534 (2008/09/18)
Reactions of 2′-hydroxy chalcone dibromides 2a-1 with phenyl hydrazine and hydrazine hydrate afford pyrazoles 1a-1 and with hydroxylamine hydrochloride give isoxazoles 5a-f in triethanolamine medium. Similarly reaction of β-diketone 3b-e with phenyl hydra
