Check Digit Verification of cas no

The CAS Registry Mumber 109423-11-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,2 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109423-11:
(8*1)+(7*0)+(6*9)+(5*4)+(4*2)+(3*3)+(2*1)+(1*1)=102
102 % 10 = 2
So 109423-11-2 is a valid CAS Registry Number.

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.
