Check Digit Verification of cas no

The CAS Registry Mumber 1233717-10-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,7,1 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1233717-10:
(9*1)+(8*2)+(7*3)+(6*3)+(5*7)+(4*1)+(3*7)+(2*1)+(1*0)=126
126 % 10 = 6
So 1233717-10-6 is a valid CAS Registry Number.

New hydrazyl derivatives with multiple properties

Tudose, Madalina,Angelescu, Daniel,Ionita, Gabriela,Caproiu, Miron T.,Ionita, Petre

experimental part, p. 182 - 185 (2010/08/07)

4-(N',N'-diphenylhydrazino)-3,5-dinitrobenzoic acid in reaction with 4-hydroxy-tempo, 4-aminobenzo-15- crown-5, and 1-bromoacetyl-pyrene, yielded the corresponding esters or amides, as yellow compounds. These hydrazines, by oxidation with lead dioxide, converted into the stable hydrazyl free radicals, with a purple-violet color. Same yellow hydrazines in reaction with alkali bases are converted into the corresponding salt of green color. The newly synthesized compounds were characterized by elemental analysis, IR, UV-Vis, 1H- and 13C-NMR, and EPR (where applicable). Acid- base, redox, fluorescence and complexation properties were also studied and discussed.
