175553-31-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 175553-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,5,5 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 175553-31:
(8*1)+(7*7)+(6*5)+(5*5)+(4*5)+(3*3)+(2*3)+(1*1)=148
148 % 10 = 8
So 175553-31-8 is a valid CAS Registry Number.

Radiochemical labeling of MDL 105725 using the secondary labeling precursor 2-[18F]fluoroethyltosylate ([18F]FETos) was carried out in yields of ~90% synthesizing [18F]MHMZ in a specific activity of ~50 MBq/nmol with a sta

The "reverse-tethered" ruthenium (II) catalyst for asymmetric transfer hydrogenation: Further applications

Morris, David J.,Hayes, Aidan M.,Wills, Martin

, p. 7035 - 7044 (2007/10/03)

The attachment of a tethering group from the basic nitrogen atom to the arene ligand of a ruthenium(II) catalyst greatly improves its ability to catalyze asymmetric transfer hydrogenation (ATH) reactions. In this paper, we describe further applications of this versatile system to an extended substrate range.
