Check Digit Verification of cas no

The CAS Registry Mumber 1141880-21-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,1,8,8 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1141880-21:
(9*1)+(8*1)+(7*4)+(6*1)+(5*8)+(4*8)+(3*0)+(2*2)+(1*1)=128
128 % 10 = 8
So 1141880-21-8 is a valid CAS Registry Number.

Reactions of 2,2-diphenyl-1-picrylhydrazyl (DPPH) with two syringylic phenols or one aroxide derivative

Hristea, Elena N.,Covaci-C?mpeanu, Irina C.,Ioni?ǎ, Gabriela,Ioni?ǎ, Petre,Draghici, Constantin,Cǎproiu, Miron T.,Hillebrand, Mihaela,Constantinescu, Titus,Balaban, Alexandru T.

body text, p. 626 - 634 (2009/07/17)

The reactions between excess 2,2-diphenyl-1-picrylhydrazyl (DPPH) and either 4-hydroxy-3,5-dimethoxybenzaldehyde (syringaldehyde, 1) or methyl 4-hydroxy-3,5-dimethoxyben-zoate (methyl syringate, 2) afford different products from those obtained with the corresponding aroxide (3)of l.In the former case (with the free phenols) the aryloxy (syringyl) group substitutes the 4-nitro group of DPPH, yielding dinitro products 7 and 8 (new stable free radicals) and 9 and 10 (corresponding hydrazines), whereas in the latter case (with the sodium aroxide 3) the aryloxy (syringyl) group substitutes one of the phenyl groups of DPPH in the para position, forming trinitro products 14 (new stable free radical) and 15 (corresponding hydrazine). Accompanying products were isolated by TLC and identified by their 1H NMR, 13C NMR, UV/Vis, and EPR spectra. The reaction mechanisms involving hy-drazyl and aroxyl free radicals are discussed.
