Check Digit Verification of cas no

The CAS Registry Mumber 4208-54-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,0 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4208-54:
(6*4)+(5*2)+(4*0)+(3*8)+(2*5)+(1*4)=72
72 % 10 = 2
So 4208-54-2 is a valid CAS Registry Number.

Chemoenzymatic approach to optically active 4-hydroxy-5-alkylcyclopent-2- en-1-one derivatives: An application of a combined circular dichroism spectroscopy and DFT calculations to assignment of absolute configuration

Frelek, Jadwiga,Karchier, Micha?,Madej, Daria,Michalak, Karol,R?zański, Pawe?,Wicha, Jerzy

, p. 300 - 306 (2014)

A series of representative optically active derivatives of 4-hydroxy-5-alkylcyclopent-2-en-1-one were prepared from the respective 2-furyl methyl carbinols via the Piancatelli rearrangement followed by the enzymatic kinetic resolution of racemates. Applicability of chiroptical methods (experimental and calculated electronic circular dichroism [ECD] and vibrational circular dichroism [VCD] spectra) to determine the absolute configuration of both stereogenic centers in 4-hydroxy-5-methylcyclopent-2-en-1-one was demonstrated. It was also demonstrated that the concurrent application of ECD and VCD spectroscopy can be used for the determination of the configuration of two stereogenic centers.

N-Heterocyclic Carbene-Catalyzed Decarboxylative Alkylation of Aldehydes

Ishii, Takuya,Kakeno, Yuki,Nagao, Kazunori,Ohmiya, Hirohisa

supporting information, p. 3854 - 3858 (2019/04/25)

We found that N-heterocyclic carbene catalysis promoted the unprecedented decarboxylative coupling of aryl aldehydes and tertiary or secondary alkyl carboxylic acid-derived redox-active esters to produce aryl alkyl ketones. The mild and transition-metal-free reaction conditions are attractive features of this method. The power of this protocol was demonstrated by the functionalization of pharmaceutical drugs and natural product. A reaction pathway involving single electron transfer from an enolate form of Breslow intermediate to a redox ester followed by recombination of the resultant radical pair to form a carbon-carbon bond is proposed.

RUTHENIUM COMPLEX AND PROCESS FOR PRODUCING TERT-ALKYL ALCOHOL THEREWITH

-

Page/Page column 7-8, (2010/11/28)

A tert-alkyl ketone, pinacolone was hydrogenated under pressurized hydrogen in the presence of a ruthenium complex (S)-1 and a base, and corresponding (S)-3,3,-dimethyl-2-butanol was thereby obtained in 100% yield and 97% ee.
