172228-59-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 172228-59-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,2,2 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 172228-59:
(8*1)+(7*7)+(6*2)+(5*2)+(4*2)+(3*8)+(2*5)+(1*9)=130
130 % 10 = 0
So 172228-59-0 is a valid CAS Registry Number.

Iridium-promoted conversion of chlorosilanes to alkynyl derivatives in a one-pot reaction sequence

Kownacki, Ireneusz,Orwat, Bartosz,Marciniec, Bogdan

supporting information, p. 3051 - 3059 (2014/07/08)

By making use of the catalytic potential of the iridium system [{Ir(μ-Cl)(CO)2}2]/NEt(i-Pr)2 in the synthesis of silyl-functionalized alkynes via silylative coupling of terminal alkynes/diynes with iodosilanes, we propose

An efficient and simple method for the preparation of symmetrical disiloxanes from hydrosilanes by Lewis acid-catalyzed air oxidation

Sridhar, Madabhushi,Ramanaiah, Beeram China,Narsaiah, Chinthala,Kumara Swamy, Mudam,Mahesh, Bellam,Kumar Reddy, Mallu Kishore

experimental part, p. 7166 - 7168 (2010/02/27)

Symmetrical disiloxanes were prepared in high yields by air oxidation of mono, di, and trihydrosilanes under Lewis acid catalysis.

Highly selective oxidation of organosilanes to silanols with hydrogen peroxide catalyzed by a lacunary polyoxotungstate

Ishimoto, Ryo,Kamata, Keigo,Mizuno, Noritaka

supporting information; experimental part, p. 8900 - 8904 (2010/01/16)

Silanol synthesis: Divacant lacunary polyoxotungstate (nBu4N+)4[g- SiW10O34(H2O)2] (I) is an efficient homogeneous catalyst for highly selective oxidation of organosilanes to silanols with 30/60% aqueous H2O2. Various kinds of silanes 1 containing aryl, alkyl, alkenyl, alkynyl and alkoxy groups are chemoselectively converted into the corresponding silanols 2 in high yields with only one equivalent of aqueous H2O2 with respect to the substrate.

A convenient synthesis of alkynylsilanes by silylation of copper(I) alkynides

Sugita, Hikaru,Hatanaka, Yasuo,Hiyama, Tamejiro

, p. 379 - 380 (2007/10/03)

Alkynylation of chlorosilanes with copper(I) alkynides takes place smoothly in the presence of triphenylphosphine, N, N, N′, N′-tetramethylethylenediamine, or zinc powder to give a variety of alkynylsilanes in good yields.
