Check Digit Verification of cas no

The CAS Registry Mumber 74145-48-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,4 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74145-48:
(7*7)+(6*4)+(5*1)+(4*4)+(3*5)+(2*4)+(1*8)=125
125 % 10 = 5
So 74145-48-5 is a valid CAS Registry Number.

Tripod-like compounds: Syntheses of tris(p- or o-amino phenoxymethyl)-propane, tris(p- or o-amino phenoxyethyl)amine, and their schiff base or salicyl derivatives

Lu,Fan,Zhao,Wu

, p. 1531 - 1540 (2007/10/03)

Tris(nitrophenoxymethyl)propane and tris(nitrophenoxyethyl)amine, prepared by the reaction of trimethylol propane or triethanol amine with p- or o-chloronitrobenzene, were reduced to give the corresponding amines. The amines condensed with 2-pyridinecarboxaldehyde, 2-quinoline-carboxaldehyde, or salicylaldehyde to give the tripod Schiff bases. The tripodal salicylamides were obtained by condensation of salicylic acid with the amines in the presence of phosphorus trichloride.
