1242587-69-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1242587-69-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,5,8 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1242587-69:
(9*1)+(8*2)+(7*4)+(6*2)+(5*5)+(4*8)+(3*7)+(2*6)+(1*9)=164
164 % 10 = 4
So 1242587-69-4 is a valid CAS Registry Number.

4-Isoxazolines and pyrroles from allenoates
Lopes, Susana M.M.,Nunes, Claudio M.,Pinho E Melo, Teresa M.V.D.
experimental part, p. 6078 - 6084 (2010/09/15)
The synthesis of 4-isoxazolines via 1,3-dipolar cycloaddition of nitrones generated from allenoates and the subsequent thermal rearrangement to pyrroles is reported. The selection of the reaction conditions allowed the isolation of the initial 1,3-dipolar
