6509-75-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6509-75-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,0 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6509-75:
(6*6)+(5*5)+(4*0)+(3*9)+(2*7)+(1*5)=107
107 % 10 = 7
So 6509-75-7 is a valid CAS Registry Number.

Photoredox Catalytic Phosphite-Mediated Deoxygenation of α-Diketones Enables Wolff Rearrangement and Staudinger Synthesis of β-Lactams

Jiang, Zhiyong,Li, Haijun,Wei, Guo,Yang, Hui

supporting information, p. 19696 - 19700 (2021/08/03)

A novel visible-light-driven catalytic activation of C=O bonds by exploiting the photoredox chemistry of 1,3,2-dioxaphospholes, readily accessible from α-diketones and trialkyl phosphites, is reported. This mild and environmentally friendly strategy provides an unprecedented and efficient access to the Wolff rearrangement reaction which traditionally entails α-diazoketones as precursors. The resulting ketenes could be precisely trapped by alcohols/thiols to give α-aryl (thio)acetates and by imines to afford the valuable β-lactams in up to 99 % yields.
