Check Digit Verification of cas no

The CAS Registry Mumber 461461-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,1,4,6 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 461461-89:
(8*4)+(7*6)+(6*1)+(5*4)+(4*6)+(3*1)+(2*8)+(1*9)=152
152 % 10 = 2
So 461461-89-2 is a valid CAS Registry Number.

Yeast supported gold nanoparticles: an efficient catalyst for the synthesis of commercially important aryl amines

Krishnan, Saravanan,Patel, Paresh N.,Balasubramanian, Kalpattu K.,Chadha, Anju

supporting information, p. 1915 - 1923 (2021/02/06)

Candida parapsilosisATCC 7330 supported gold nanoparticles (CpGNP), prepared by a simple and green method can selectively reduce nitroarenes and substituted nitroarenes with different functional groups like halides (-F, -Cl, -Br), olefins, esters and nitriles using sodium borohydride. The product aryl amines which are useful for the preparation of pharmaceuticals, polymers and agrochemicals were obtained in good yields (up to >95%) using CpGNP catalyst under mild conditions. The catalyst showed high recyclability (≥10 cycles) and is a robust free flowing powder, stored and used after eight months without any loss in catalytic activity.

Ultrahigh performance bio-based polyimides from 4,4′-diaminostilbene

Kumar, Amit,Tateyama, Seiji,Yasaki, Katsuaki,Ali, Mohammad Asif,Takaya, Naoki,Singh, Rajeev,Kaneko, Tatsuo

, p. 182 - 189 (2016/01/09)

We have developed a novel route for the synthesis of high-performance bio-polyimides (PIs) microbially-derived from photo-responsive aromatic diamine 4,4′-diaminostilbene (DAS) and its reduced counterpart 4, 4′-(ethane-1,2-diyl)dianiline (EDDA). DAS and EDDA were condensed with various commercially-available dianhydrides to obtain a series of poly(amic acid)s (PAAs) and PIs which were characterized in terms of their thermal, mechanical, and photo-functions. These bio-based PAAs showed a very high viscosity of 6.62 dL/g, and the PIs showed ultrahigh thermal resistance with Td10 values over 600 °C, which were higher than that of any bio-based plastic reported thus far. They also showed Tg values above 250 °C, and tensile strength of over 132 MPa, which is higher than that of Kapton. The PIs also showed photo-functional behavior based on stilbene-based photoreactions.

Facile synthesis of biologically active heterocycles by indium-induced reactions of aromatic nitro compounds in aqueous ethanol

Banik, Bimal K.,Banik, Indrani,Samajdar, Susanta,Wilson, Mary

, p. 283 - 296 (2007/10/03)

Indium/ammonium chloride-induced reduction of aromatic nitro compounds to aromatic amines in aqueous ethanol was developed. Useful chemoselectivity was observed in the reduction reaction. This method was extended to reductive cyclization and rearrangement toward the synthesis of various biologically active heterocycles, including quinoline, oxazines, quinalonones, and phenanthridine in excellent yield. The oxophilicity of indium metal influenced the reaction in aqueous ethanol. Metals like zinc and tin were not effective in promoting this kind of reactions under the present environmentally friendly conditions.
