32539-24-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 32539-24-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,5,3 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 32539-24:
(7*3)+(6*2)+(5*5)+(4*3)+(3*9)+(2*2)+(1*4)=105
105 % 10 = 5
So 32539-24-5 is a valid CAS Registry Number.

, p. 2737 - 2749 (1998)
Selective N-alkylation of 3-oxo-3,4-dihydro-2H-1,4-benzoxazine-2- carboxylates is achieved under phase transfer catalysis. Alkylation of 4- alkyl-3-oxo-3,4-dihydro-2H-1,4-benzoxazine-2-carboxylates at position 2 using sodium hydride as a base affords 2,4-
