40662-66-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40662-66-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,6 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40662-66:
(7*4)+(6*0)+(5*6)+(4*6)+(3*2)+(2*6)+(1*6)=106
106 % 10 = 6
So 40662-66-6 is a valid CAS Registry Number.

Four-Component Radical Dual Difunctionalization (RDD) of Two Different Alkenes with Aldehydes and tert-Butyl Hydroperoxide (TBHP): An Easy Access to β,δ-Functionalized Ketones

Wu, Chuan-Shuo,Liu, Ren-Xiang,Ma, Da-You,Luo, Cui-Ping,Yang, Luo

, p. 6117 - 6121 (2019)

A convenient Fe-catalyzed four-component radical dual difunctionalization and ordered assembly of two alkenes with aromatic/aliphatic aldehydes and TBHP to provide chain elongated β,δ-functionalized ketones via a one-pot procedure has been developed. Alde

Photocatalysis with Quantum Dots and Visible Light: Selective and Efficient Oxidation of Alcohols to Carbonyl Compounds through a Radical Relay Process in Water

Zhao, Lei-Min,Meng, Qing-Yuan,Fan, Xiang-Bing,Ye, Chen,Li, Xu-Bing,Chen, Bin,Ramamurthy, Vaidhyanathan,Tung, Chen-Ho,Wu, Li-Zhu

supporting information, p. 3020 - 3024 (2017/03/13)

Selective oxidation of alcohols to aldehydes/ketones has been achieved with the help of 3-mercaptopropionic acid (MPA)-capped CdSe quantum dot (MPA-CdSe QD) and visible light. Visible-light-prompted electron-transfer reaction initiates the oxidation. The thiyl radical generated from the thiolate anion adsorbed on a CdSe QD plays a key role by abstracting the hydrogen atom from the C?H bond of the alcohol (R1CH(OH)R2). The reaction shows high efficiency, good functional group tolerance, and high site-selectivity in polyhydroxy compounds. The generality and selectivity reported here offer a new opportunity for further applications of QDs in organic transformations.
