4521-03-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4521-03-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,2 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4521-03:
(6*4)+(5*5)+(4*2)+(3*1)+(2*0)+(1*3)=63
63 % 10 = 3
So 4521-03-3 is a valid CAS Registry Number.

Furano Compounds: Part IL - Solvolytic Rearrangement of Ketoximes in Benzofuran Series and PMR Study of Benzofuryl-2-alkyl(aryl) Ketoximes

Chatterjea, J. N.,Singh, K. R. R. P.

, p. 1053 - 1056 (2007/10/02)

Solvolytic rearrangement of tosylates of 3-alkyl(aryl)-benzofuryl-2-alkyl ketoximes and 2-substituted(and unsubstituted)benzofuryl-3-methyl ketoximes with aqueous methanol depends upon their configurations.The tosylates of 2-ethyl(benzyl)benzofuryl-3-methyl ketoximes obtained in alkaline medium do not undergo solvolytic rearrangement under similar conditions.The isomerisation of anti-isomers of the above mentioned ketoximes to syn-forms with hydrogen chloride is unsuccesful.The configurations of syn- and anti-isomers of benzofuryl-2-alkyl(aryl) ketoximes have been studied by PMR spectroscopy.
