84494-64-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 84494-64-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,9 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84494-64:
(7*8)+(6*4)+(5*4)+(4*9)+(3*4)+(2*6)+(1*4)=164
164 % 10 = 4
So 84494-64-4 is a valid CAS Registry Number.

Synthesis of 2,4,5-triphenyl-substituted oxazolidine and 2,5-diphenyl-substituted pyrrolidine derivatives

Wittland, Claudia,Arend, Michael,Risch, Nikolaus

, p. 367 - 371 (2007/10/03)

A simple one-pot domino reaction procedure for the stereoselective synthesis of oxazolidines and C2-symmetric pyrrolidines from inexpensive starting materials is described. Azomethine ylides generated in situ by heating a mixture of benzaldehyde and benzylic amines are trapped with dipolarophiles by a 1,3-dipolar cycloaddition reaction. The products represent valuable synthetic building blocks or potential starting materials for the preparation of chiral auxiliaries and are difficult to obtain by other methods.

AZIRIDINES-IV CATALYTIC DECOMPOSITION OF PHENYLDIAZOMETHANE IN SCHIFF'S BASES

Bartnik, R.,Mloston, G.

, p. 2569 - 2576 (2007/10/02)

Catalytic decomposition of phenyldiazomethane in Schiff's bases is found to proceed via formation of trans-1,3-dipole (azomethine ylide) as an intermediate product.Depending on the size and quantity of the substituents, the ylide undergoes either cyclizat
