Check Digit Verification of cas no

The CAS Registry Mumber 35486-42-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,4,8 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 35486-42:
(7*3)+(6*5)+(5*4)+(4*8)+(3*6)+(2*4)+(1*2)=131
131 % 10 = 1
So 35486-42-1 is a valid CAS Registry Number.

A Porous Organic Polymer Nanotrap for Efficient Extraction of Palladium

Aguila, Briana,Al-Enizic, Abdullah M.,Cassady, Harper C.,Liang, Zhiqiang,Ma, Shengqian,Meulenberg, Robert W.,Nafadyc, Ayman,Shan, Chuan,Sun, Qi,Wright, Joshua T.

, p. 19618 - 19622 (2020)

To offset the environmental impact of platinum-group element (PGE) mining, recycling techniques are being explored. Porous organic polymers (POPs) have shown significant promise owing to their selectivity and ability to withstand harsh conditions. A series of pyridine-based POP nanotraps, POP-Py, POP-pNH2-Py, and POP-oNH2-Py, have been designed and systematically explored for the capture of palladium, one of the most utilized PGEs. All of the POP nanotraps demonstrated record uptakes and rapid capture, with the amino group shown to be vital in improving performance. Further testing on the POP nanotrap regeneration and selectivity found that POP-oNH2-Py outperformed POP-pNH2-Py. Single-crystal X-ray analysis indicated that POP-oNH2-Py provided a stronger complex compared to POP-pNH2-Py owing to the intramolecular hydrogen bonding between the amino group and coordinated chlorine molecules. These results demonstrate how slight modifications to adsorbents can maximize their performance.

Novel synthesis method of crizotinib intermediate (by machine translation)

-

Paragraph 0024, (2021/01/04)

The invention relates to a synthesis method of an organic compound, in particular to a novel synthesis method of a crizotinib intermediate, which comprises the following steps: taking cheap and easily available 2,6 - dichloro -3 - fluoroacetophenone as a starting raw material and reducing the CBS system to obtain S-shaped chiral alcohol. , 2 - Aminopyridine is taken as a raw material and bromine is brominated to obtain 3,5 - dibromo -2 - aminopyridine. The compound is condensed into an ether with a chiral alcohol under the action of an acid-binding agent to obtain the intermediate of the required configuration. The method is simple in reaction, short in route, less in three wastes, environment-friendly, high in yield of all steps, and less in raw material and reagent waste. (by machine translation)

Preparation method of 2-amino substituted six-membered nitrogen-containing heterocycle complex

-

Paragraph 0025; 0026; 0087, (2019/02/08)

The invention discloses a preparation method of a 2-amino substituted six-membered nitrogen-containing heterocycle complex. The preparation method comprises the following steps: mix 2-fluorine substituted six-membered nitrogen-containing heterocycle complex and amidine hydrochloride salt compound, and then react under the action of a alkaline substance to obtain a 2-amino substituted six-memberednitrogen-containing heterocycle complex. Preferably, the 2-amino substituted six-membered nitrogen-containing heterocycle complex is a 2-amino pyridine compound, a 2-aminopyrimidine compound or a 2-aminopyrazine compound. Compared with the prior art, the method has the advantages of simple synthesis conditions, less reaction steps, mild reaction conditions, low cost of the catalyst used, less waste discharge and good functional group tolerance.
