5070-24-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5070-24-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,7 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5070-24:
(6*5)+(5*0)+(4*7)+(3*0)+(2*2)+(1*4)=66
66 % 10 = 6
So 5070-24-6 is a valid CAS Registry Number.

Oxidative Generation of α-Radicals of Carbonyl Compounds from the α-Stannyl Derivatives and Their Reactions with Electron-Rich Olefins

Kohno, Yasushi,Narasaka, Koichi

, p. 322 - 329 (2007/10/02)

The oxidation of α-tributylstannyl alkanoates with tetrabutylammonium hexanitratocerate(IV) generates α-radicals of the alkanoates by eliminating the stannylium ion.The thus-formed radicals react with various electron-rich olefinic compounds, such as silyl enol ethers, giving addition products in good yield.This method formally achieves selective cross coupling between alkanoates and ketones.

Oxovanadium-Induced Oxidative Desilylation for the Selective Synthesis of 1,4-Diketones

Fujii Takashi,Hirao, Toshikazu,Ohshiro, Yoshiki

, p. 5823 - 5826 (2007/10/02)

Silyl enol ethers underwent the VO(OR)Cl2-induced homo- or cross-coupling giving 1,4-diketones selectively via one-electron oxidative desilylation.

DEHYDRODIMERIZATION OF KETONES, CARBOXYLIC ACIDS, AMIDES, ESTERS, ALCOHOLS, AND AMINES, VIA MERCURY-PHOTOSENSITIZATION

Boojamra, Constantine G.,Crabtree, Robert H.,Ferguson, Richard R.,Muedas, Cesar A.

, p. 5583 - 5586 (2007/10/02)

Selective dehydrodimerization of the title compounds can be carried out on a preparative scale at 1 atm. and at 25-110 deg C in a simple apparatus by Hg-photosensitized reaction under H2.
