18430-74-5 Usage
Preparation
Preparation by Fries rearrangement of 2,4-dichlorophenyl propionate (b.p.14 148°) with aluminium chloride, at 155°, following Hartung’s procedure or at 165–175° for 40 min (76%).
Check Digit Verification of cas no
The CAS Registry Mumber 18430-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,3 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18430-74:
(7*1)+(6*8)+(5*4)+(4*3)+(3*0)+(2*7)+(1*4)=105
105 % 10 = 5
So 18430-74-5 is a valid CAS Registry Number.

Regioselective synthesis of 3,5-diaryl-4-methylisoxazoles
Lokhande, Pradeep D.,Hasanzadeh, Kamal,Khaledi, Hamid,Ali, Hapipah Mohd
, p. 237 - 245 (2013/07/27)
A new class of isoxazole derivatives, namely 2-(3-aryl-4-methylisoxazol-5- yl)phenols, has been efficiently synthesized through the regioselective reaction of 2-aryl-3-methylchromones with hydroxylamine. The products were characterized by spectroscopic me
