Check Digit Verification of cas no
The CAS Registry Mumber 105174-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,1,7 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 105174-97:
(8*1)+(7*0)+(6*5)+(5*1)+(4*7)+(3*4)+(2*9)+(1*7)=108
108 % 10 = 8
So 105174-97-8 is a valid CAS Registry Number.

Process for the preparation of 3,5-disubstituted isoxazoles
-
, (2008/06/13)
A novel process for the preparation of 3-bromo- and 3-chloro-5-substituted isoxazoles is provided. Dibromo- or dichloro-formaldoxime is reacted with an excess of an 1-alkyne derivative of the formula where R is hydrogen, phenyl or 1-6 C alkyl optionally substituted by halogen, OH, OR', CHO, COR', COOR', CONH2, CONR'R" or NHCOR' where, in turn, R' and R", which may be the same or different, are a 1-6 C alkyl or haloalkyl, in the presence of (i) at least an equimolecular amount, with respect to the dibromo- or dichloro-formaldoxime, of an alkaline base selected from the class consisting of sodium and potassium carbonate and bicarbonate and (ii) an inert solvent in which the 1-alkyne is soluble at room temperature.
