1023299-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1023299-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,2,9 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1023299-40:
(9*1)+(8*0)+(7*2)+(6*3)+(5*2)+(4*9)+(3*9)+(2*4)+(1*0)=122
122 % 10 = 2
So 1023299-40-2 is a valid CAS Registry Number.

Synthesis of aminoalkylpyrazoles and-isoxazoles from cyclic β-(trifluoroacetyl) enamines
Nenajdenko,Pronin,Balenkova
, p. 336 - 344 (2008/03/11)
A method for the synthesis of cyclic β-(trifluoroacetyl) enamines was proposed. Reactions of the latter with hydrazine and hydroxylamine gave pyrazoles and isoxazoles, respectively, containing trifluoromethyl and ω-aminoalkyl fragments. Addition of hydraz
