Check Digit Verification of cas no
The CAS Registry Mumber 119-51-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119-51:
(5*1)+(4*1)+(3*9)+(2*5)+(1*1)=47
47 % 10 = 7
So 119-51-7 is a valid CAS Registry Number.

Convenient synthesis of 4,5-unsubstituted 3-aroylisoxazoles from methyl aryl ketones and (vinylsulfonyl)benzene in water
Wang, Liang,Tao, Yu,Zhang, Nana,Li, Shubai
, (2021)
A convenient synthesis of 3-aroylisoxazoles from methyl ketones and (vinylsulfonyl)benzene in 2%TPGS-750-M/H2O has been developed. This reaction proceeds via tandem tert-butyl nitrite-promoted Csp3-H functionalization of methyl ketones, 1,3-dipolar cycloaddition and base-catalyzed aromatization, providing the corresponding products in moderate to good yields.
Visible-Light Photoredox-Catalyzed Dicarbofunctionalization of Styrenes with Oxime Esters and CO2: Multicomponent Reactions toward Cyanocarboxylic Acids and γ-Keto Acids

A photoredox-catalyzed dicarbofunctionalization of styrenes with oxime esters and CO2 has been achieved. Notably, a series of four-, five-, or six-membered cyclic ketone oximes worked well to furnish a wide range of ε-, ζ-, and η-cyanocarboxylic acids in good yields. Furthermore, a series of γ-keto acids also could be obtained by employing acyclic ketone oxime esters as the carbonyl radical precursor. It provides convergent access to diverse biologically important cyanocarboxylic and γ-keto acids.
NOVEL PROCESS FOR THE PREPARATION OF R-PHENYLACETYLCARBINOL AND β-AMINOALCOHOLS

Page/Page column 8; 9, (2020/07/14)
Disclosed herein is a process for the manufacture of (R)-phenylacetylcarbinol ((R)-PAC), (1R,2S). Ephedrine and its salts, (1R,2S)-norephedrine and its salts and 1-(Phenyl/Substituted phenyl)-2-(amino/alkylamino/dialklyamino) propan-1-ol and its salts, by enzymatic reduction of α-isonitrosopropiophenone (INP) and substituted α-isonitrosopropiophenone (substituted INP). The β-amino alcohols, produced by the process of present invention gives their corresponding diastereomers on Walden inversion. The present preparation process of (R)-PAC with (R)-PAC oxime as an intermediate has the advantage, that propiophenone as a key raw material which is easily available and has a low-price, operationally simple with high yield and a single process leading to the synthesis of several 1,2-aminoalcohol/ β- aminoalcohols active pharmaceutical ingredients. The design approach of the process is to reduce environmental impact of the product by comparing to the present manufacturing process.
