32328-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 32328-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,3,2 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 32328-81:
(7*3)+(6*2)+(5*3)+(4*2)+(3*8)+(2*8)+(1*1)=97
97 % 10 = 7
So 32328-81-7 is a valid CAS Registry Number.

Rueping, Magnus,Sugiono, Erli,Theissmann, Thomas,Kuenkel, Alexander,Kockritz, Angela,Pews-Davtyan, Anahit,Nemati, Navid,Beller, Matthias

, p. 1065 - 1068 (2007)

(Chemical Equation Presented) The enantioselective Bronsted acid catalyzed addition of methyleneaminopyrrolidine to N-Boc imines has been achieved in the presence of chiral phosphoric acids derived from 3,3′-di(phenanthryl)-H8-BINOL. The corresponding ami

Revisitation of Formaldehyde Aniline Condensation. VII. 1,3,5-Triarylhexahydro-sym-triazines and 1,3,5,7-Tetraaryl-1,3,5,7-tetrazocines from Aromatic Amines and Paraformaldehyde

Giumanini, Angelo G.,Verardo, Giancarlo,Zangrando, Ennio,Lassiani, Lucia

, p. 1087 - 1103 (2007/10/02)

A product study of the reaction between a number of aromatic amines substituted with widely different groups and paraformaldehyde in inert solvents was performed and found to yield 1,3,5-triaryl-1,3,5-hexahydrotriazines, 1,3,5,7-tetraaryl-1,3,5,7-tetrazocines and formaminals.It was not possible to correlate the product outcomes with the actual structure of the amine substrate.The X-ray diffraction structural determination of 1,3,5-tri-(t-butylphenyl)- (1b) and 1,3,5-tri-(m-fluorophenyl)-1,3,5-hexahydrotriazine (1c) showed the diaxial arrangement of the N-substituents.
