Check Digit Verification of cas no

The CAS Registry Mumber 625-01-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 625-01:
(5*6)+(4*2)+(3*5)+(2*0)+(1*1)=54
54 % 10 = 4
So 625-01-4 is a valid CAS Registry Number.

Application of sulfonyl type compounds as chlorination reagent

-

Paragraph 0026-0030, (2020/08/27)

The invention discloses an application of a sulfonyl type compound as a chlorination reagent. The structural formula of the sulfonyl type compound is shown as the following formula (I); in formula (I), the R is a substituted or unsubstituted linear or branched alkyl group with 1 to 30 carbon atoms, which means that the alkyl group can be substituted by halogen, alkoxy with 1 to 20 carbon atoms andaryl with 6 to 14 carbon atoms, and the aryl with 6 to 14 carbon atoms can be further substituted by alkyl with 1 to 20 carbon atoms, alkoxy with 1 to 20 carbon atoms and halogen. The sulfonyl compound can perform single chlorination on carbonyl alpha-sites of organic molecules such as aldehyde, ketone, esters and the like with high selectivity under mild conditions; so that the compound can solve the safety problem of existing chlorination reagents such as chlorine, sulfonyl chloride and the like in the use process, reduces post-treatment and three-waste treatment steps, and is suitable forindustrial-scale production.

supporting information; experimental part, p. 4100 - 4102 (2012/07/14)

Nineteen previously unreported matrine derivatives were synthesized and characterized using elemental analysis, infrared spectroscopy, proton nuclear magnetic resonance spectroscopy, and mass spectrometry. Target compounds 6a-6l and 7a-7c showed stronger inhibitory activities than matrine in the in vitro antitumor tests and inhibited the growth of the Hep7402, B16-F10, A549, and TW03 cell lines. In addition, compound 6i exhibited a potent antitumor activity similar to that of colchicine.

Reaction of aryl sulfonic acid ester and amines

-

, (2008/06/13)

Oil-soluble, nitrogen-containing compositions, useful as lubricating oil additives, are provided. These compositions are prepared by reacting: (a) an aryl ester of a hydrocarbylethylsulfonic acid; or (b) a hydrocarbylsulfonyl chloride with a nitrogen-containing compound containing at least one amine hydrogen, i.e., --NH function. Also provided are processes for preparing these compositions and lubricating oil additive concentrates and lubricating oil compositions containing these compositions.
