Check Digit Verification of cas no
The CAS Registry Mumber 119-72-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 119-72:
(5*1)+(4*1)+(3*9)+(2*7)+(1*2)=52
52 % 10 = 2
So 119-72-2 is a valid CAS Registry Number.

Nitrogen doped carbon supported iron catalysts for highly selective production of 4,4′-diamino-2,2′-stilbenedisulfonic acid

, (2019)
Nitrogen doped carbon supported iron catalysts were prepared from pyrolysis of a multidentate nitrogen ligand iron complex supported on chitosan at different temperature, and showed good performances in the reduction of 4,4′-dinitrostilbene-2,2′-disulfonic acid (DNS acid) to 4,4′-diamino-2,2′-stilbenedisulfonic acid (DSD acid) with hydrazine hydrate (N2H4·H2O) as reductant. Characterization results revealed that the iron is mainly present in the form of Fe2O3 and metallic iron nanoparticles. The doped N atoms functionalized as anchoring sites to stabilize iron nanoparticles, which endows the catalysts with excellent activity and superior reusability.
