894810-82-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 894810-82-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,4,8,1 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 894810-82:
(8*8)+(7*9)+(6*4)+(5*8)+(4*1)+(3*0)+(2*8)+(1*2)=213
213 % 10 = 3
So 894810-82-3 is a valid CAS Registry Number.

Development of isomerization and cycloisomerization with use of a ruthenium hydride with N-heterocyclic carbene and its application to the synthesis of heterocycles

Arisawa, Mitsuhiro,Terada, Yukiyoshi,Takahashi, Kazuyuki,Nakagawa, Masako,Nishida, Atsushi

, p. 4255 - 4261 (2007/10/03)

A pure ruthenium hydride complex with N-heterocyclic carbene (NHC) ligand was efficiently generated from the reaction of a second-generation Grubbs ruthenium catalyst with vinyloxytrimethylsilane and unambiguously characterized. This ruthenium hydride complex showed high catalytic activity for the selective isomerization of terminal olefin and for the cycloisomerization of 1,6-dienes. These reactions of N-allyl-o-vinylaniline lead to novel synthetic methods for heterocycles such as indoles and 3-methylene-2,3-dihydroindoles, which are useful synthons for bioactive natural products. These procedures address an important issue in diversity-oriented synthesis.
