74959-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74959-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,5 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74959-20:
(7*7)+(6*4)+(5*9)+(4*5)+(3*9)+(2*2)+(1*0)=169
169 % 10 = 9
So 74959-20-9 is a valid CAS Registry Number.

Intramolecular 1,3-Dipolar Cycloadditions of Aliphatic Nitrile Oxides
Garanti, Luisa,Zecchi, Gaetano
, p. 609 - 611 (2007/10/02)
Treatment of functionalized 1-chloro-oximes (3c and 4a,b) with triethylamine originates nitrile oxides (1c and 2a,b) which undergo an intramolecular cycloaddition providing fused-ring isoxazole derivatives (7c and 8a,b).The latter reaction was not observe
