53178-47-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53178-47-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,7 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53178-47:
(7*5)+(6*3)+(5*1)+(4*7)+(3*8)+(2*4)+(1*7)=125
125 % 10 = 5
So 53178-47-5 is a valid CAS Registry Number.

Platinum complex resistant to sulfur poisoning and applications thereof

-

Paragraph 0071; 0074; 0075; 0080-0082; 0140-0142, (2018/09/29)

The invention discloses a platinum complex resistant to sulfur poisoning and applications thereof. The platinum complex has a complexing symmetric structure, which comprises a 1,3-dithiane benzene containing derivative group and symmetric unsaturated epithio-silane; wherein the 1,3-dithiane benzene containing derivative group comprises a benzene ring and a symmetric epithio- six-membered ring. ThePt catalyst has a highly symmetrical complexing structure and a very good effect on resisting sulfur poisoning. The catalytic activity is 92% or more. The catalytic effect in a sulfur system is basically the same as that in a non-sulfur system. The Pt catalyst has a good performing on resisting sulfur poisoning, is very stable at a room temperature, and can be stored for a long term. Solved are the problems that in the prior art, the storage time of a conventional Pt catalyst is short, the conventional Pt catalyst should be strictly sealed, and the catalytic activity of the Pt catalyst is lost after the Pt catalyst is poisoned by sulfur containing compounds. The Pt catalyst can be widely used in silicon-hydrogen addition reactions.

A Novel 1,3-Dithiane-based Cyclopenta-annellation Procedure: Synthesis of the Rocaglamide Skeleton

Davey, Andrew E.,Taylor, Richard J. K.

, p. 25 - 27 (2007/10/02)

A novel three carbon cyclopentanone annellation procedure, based on direct 1,3-dithiane lithiation followed by intramolecular carbonyl addition, has been employed in a synthetic approach to the anti-cancer compound, rocaglamide.
