Check Digit Verification of cas no

The CAS Registry Mumber 619-90-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 619-90:
(5*6)+(4*1)+(3*9)+(2*9)+(1*0)=79
79 % 10 = 9
So 619-90-9 is a valid CAS Registry Number.

An efficient, economical and eco-friendly acylation of alcohols and amines by alum doped nanopolyaniline under solvent free condition

Behera, Satyaranjan,Patra, Braja N.

, (2021/08/06)

We report acylation of alcohols and amines employing acetic acid as an acylating agent in solvent free condition by using alum doped nanopolyaniline (NDPANI) as a catalyst. This environmentally benign method does not use corrosive acid anhydrides and acid chlorides for acylation and does not produce waste product. Also, a non-toxic potash alum was used for doping of polyaniline rather than corrosive acids. The reaction conditions represent an advance over established method not only in omitting the need for expensive catalysts or solvents but also in shortening the reaction time significantly. The advantages of this catalyst are non-hazardous, cheap, reusable, easy to prepare and handling.

Recyclable DMAP-Functionalized polymeric nanoreactors for highly efficient acylation of alcohols in aqueous systems

Qiu, Jiaqi,Meng, Fuliang,Wang, Maolin,Huang, Jinjin,Wang, Chengzhan,Li, Xiao,Yang, Guang,Hua, Zan,Chen, Tao

, (2021/03/30)

Fabrication of highly efficient and recyclable nanoreactors via macromolecular self-assembly represents a promising strategy for green organic transformation. In this study, small-molecule catalysts 4-(N,N-dimethylamino)pyridine (DMAP) functionalized nanoreactors were constructed by self-assembly of amphiphilic block copolymers with DMAP moieties in the hydrophobic block, leading to heterogeneous catalysts with excellent dispersity in water. The key preparation route included reversible addition-fragmentation chain transfer (RAFT) polymerization of 2-(N-methyl-N-(4-pyridyl)amino)ethyl methacrylate (MAPMA) and methyl methacrylate (MMA) using poly (oligomeric (ethylene glycol) methyl ether methacrylate) (POEGMA) as a hydrophilic macromoleculer RAFT reagent. The characterization by dynamic light scattering (DLS) and transmission electron microscopy (TEM) shows that the nanoreactors possess a core-shell nanostructure with the diameter of around 110 nm. The resulting polymeric nanoreactors showed excellent catalytic activity for acylation of alcohols in water. High conversion of a variety of alcohol (>99%) and excellent product selectivity were achieved. The high catalytic efficiency of the nanoreactors may be attributed to the enhancement of the interaction between the reactant and the catalyst in the confined hydrophobic space, which simulates how enzymes usually work. Moreover, the catalyst could be easily recovered by thermos-responsive separation and reused with high activity for more than 5 cycles. This study presents an efficient approach to achieve green catalytic reactions which are normally incompatible to aqueous conditions, potentially applicable to other catalytic systems such as metal-mediated organic transformations.
