Check Digit Verification of cas no

The CAS Registry Mumber 1320346-07-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,0,3,4 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1320346-07:
(9*1)+(8*3)+(7*2)+(6*0)+(5*3)+(4*4)+(3*6)+(2*0)+(1*7)=103
103 % 10 = 3
So 1320346-07-3 is a valid CAS Registry Number.

New N-substituted polyamines. Synthesis, characterization and crystal and molecular structure of 2-[{C6H4(CO)2NCH 2CH2}2NCH2]C6H 4Br

Coros, Maria,Domide, Dan,Vlassa, Mircea,Soran, Albert,Silvestru, Cristian

experimental part, p. 803 - 810 (2012/01/14)

New branched polyamines starting from diethylenetriamine, i.e. (Me 2NCH2CH2)2NCH2C 6H5 (9) and 2-[(Me2NCH2CH 2)2NCH2]C6H4X [X = Cl (10), Br (11)], were prepared by a multi-step procedure. Both the branched polyamines and the corresponding intermediates were characterized by multinuclear NMR spectroscopy in solution. The crystal and molecular structure of the intermediate 2-[{C6H4(CO)2NCH 2CH2}2NCH2]C6H 4Br (5) was established by single-crystal X-ray diffraction.
