17841-19-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17841-19-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,4 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17841-19:
(7*1)+(6*7)+(5*8)+(4*4)+(3*1)+(2*1)+(1*9)=119
119 % 10 = 9
So 17841-19-9 is a valid CAS Registry Number.

Highly efficient reduction of aldehydes with silanes in water catalyzed by silver

Jia, Zhenhua,Liu, Mingxin,Li, Xingshu,Chan, Alberts. C.,Li, Chao-Jun

, p. 2049 - 2056 (2013)

A highly efficient silver-catalyzed chemoselective method for the reduction of aldehydes to their corresponding alcohols in water was developed by using hydrosilanes as reducing agents. The ketones remained essentially inert under the same reaction conditions, thereby providing an additional synthetically useful chemoselectivity. Georg Thieme Verlag Stuttgart, New York.

Role of low-valent rhenium species in catalytic hydrosilylation reactions with oxorhenium catalysts

Smeltz, Jessica L.,Boyle, Paul D.,Ison, Elon A.

, p. 5994 - 5997 (2012/10/30)

The catalytic competency of a Re(III) complex has been demonstrated. In the presence of silane, oxorhenium(V) catalysts are deoxygenated to produce species that are significantly more active than the metal oxo precursors in hydrosilylation reactions. The results presented suggest that, in evaluating mechanisms for catalytic hydrosilylation reactions that involve high-valent metal oxo complexes, the activity of species that may be generated by deoxygenation of the metal with silane should also be systematically investigated as potential catalysts.
