71042-21-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71042-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,4 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71042-21:
(7*7)+(6*1)+(5*0)+(4*4)+(3*2)+(2*2)+(1*1)=82
82 % 10 = 2
So 71042-21-2 is a valid CAS Registry Number.

BODIPY protein misfolding probe Hal-BODIPY, preparation method and application thereof

-

Paragraph 0041-0043; 0046; 0047, (2021/01/29)

The invention discloses a BODIPY protein misfolding probe Halo-BODIPY, a preparation method and application thereof, wherein the structural formula of the fluorescent probe is shown as a formula I inthe specification. According to the invention, the micro

Preparation method of 1-chloro-6-iodohexane

-

Paragraph 0011; 0013, (2019/04/09)

The invention discloses a preparation method of 1-chloro-6-iodohexane. The preparation method comprises the steps of with 6-chloro-1-hexanol and p-toluene sulfochloride as the materials and benzene ortoluene as a solvent, reacting at (-5)-(5) DEG C for 2-5 hours under the effects of a phase transfer catalyst and an acid-binding agent so as to prepare 4-methylbenzenesulfonic acid-6-chlorohexyl ester, and carrying out reflux reaction on 4-methylbenzenesulfonic acid-6-chlorohexyl ester and sodium iodide for 0.5-3 hours, so as to prepare 1-chloro-6-iodohexane. The preparation method has the characteristics of easiness in operation, simplicity and convenience in after-treatment and relatively high yield.

An acid/alkali double stimulus responsive nano container and its preparation method

-

Paragraph 0039-0041; 0057; 0073, (2018/11/22)

The invention discloses an acid/base double stimulation responsive nanometer container and a preparation method thereof. According to the nanometer container, mesoporous nanometer silicon dioxide is adopted as a framework; a host-guest compound is formed based on host pillar[5]arene and a guest molecular chain 1,6-(1-(1-methyl)imida zolehexyl)hexamethylene diamine; a supramolecular valve is formed on the surface of a microsphere through modification; a metal corrosion inhibitor is loaded in the microsphere; under the action of pH stimulation, macrocyclic pillar[5]arene in the nanometer container can move, thereby achieving controllable release of the metal corrosion inhibitor; and after the metal corrosion inhibitor enters a coating, metal corrosion can be effectively inhibited. The nanometer container disclosed by the invention has the advantages that the function of response to various external stimuluses can be achieved; double response to acid/base stimulation can be achieved; and the prospect of application to the fields of drug delivery, intelligent anti-corrosive coating and the like is broad.
