Check Digit Verification of cas no
The CAS Registry Mumber 139004-02-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,0 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139004-02:
(8*1)+(7*3)+(6*9)+(5*0)+(4*0)+(3*4)+(2*0)+(1*2)=97
97 % 10 = 7
So 139004-02-7 is a valid CAS Registry Number.

Stereochemistry of N,N'-Bis--ethylenediamine
Kristen, H.,Wrubel, F.,Widuwild, H.,Luecke, L.
, p. 545 - 554 (2007/10/02)
N,N'-Bis--ethylene diamine (5), synthesized from racemic 1,2-anhydro-3-O-(o-ethoxyphenyl)-glycerol (1) and ethylene diamine (2) or N,N'-dibenzyl ethylene diamine (3) crystallized in two fractions with different melting points.Both of these analytically pure products gave identical two spot tl-chromatograms on achiral phases.Attempts were made to resolve the mixtures which proved to consist of configurative but not constitutive isomers.Optically pure products were synthesized from chiral precursors.
