6591-16-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6591-16-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,9 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6591-16:
(6*6)+(5*5)+(4*9)+(3*1)+(2*1)+(1*6)=108
108 % 10 = 8
So 6591-16-8 is a valid CAS Registry Number.

Visible light induced hydrophosphinylation of unactivated alkenes catalyzed by salicylaldehyde

Cao, Peng,Chen, Tian,Fan, Jiaye,Hu, Ping,Li, Miaomiao,Li, Qianggen,Li, Yang,Wang, Bi-Qin,Wang, Simin,Xiong, Fuying,Yuan, Zeqin

supporting information, p. 3600 - 3606 (2021/06/06)

An air and water insensitive visible light induced hydrophosphinylation of unactivated alkenes is reported. A small amount of a simple and cheap compound, salicylaldehyde, is used as a photosensitizer. The reaction is carried out in a basic aqueous solution which enables the deprotonated salicylaldehyde to show visible light absorption.

Radical phosphination of organic halides and alkyl imidazole-1- carbothioates

Sato, Akinori,Yorimitsu, Hideki,Oshima, Koichiro

, p. 4240 - 4241 (2007/10/03)

Taking advantage of a radical-based methodology, mild and chemoselective phosphination reactions of organic halide and alkyl imidazole-1-carbothioates have been developed. The mild reaction conditions allow labile functional groups to survive during the reaction. Copyright
