664346-20-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 664346-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,4,3,4 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 664346-20:
(8*6)+(7*6)+(6*4)+(5*3)+(4*4)+(3*6)+(2*2)+(1*0)=167
167 % 10 = 7
So 664346-20-7 is a valid CAS Registry Number.

Cu(I)-catalyzed oxidative cyclization of enynamides: Regioselective access to cyclopentadiene frameworks and 2-aminofurans

Shen, Wen-Bo,Tang, Xiang-Ting,Zhang, Ting-Ting,Liu, Si-Yu,He, Jiang-Man,Su, Tong-Fu

supporting information, p. 6799 - 6804 (2020/09/15)

An efficient Cu(I)-catalyzed oxidative cyclization of alkynyl-tethered enynamides for the construction of fused bicyclic cyclopentadiene derivatives is disclosed. The cascade proceeds through alkyne oxidation, carbene/alkyne metathesis, and formal (3 + 2)

Stereoselective Synthesis of Exocyclic Tetrasubstituted Vinyl Halides via Ru-Catalyzed Halotropic Cycloisomerization of 1,6-Haloenynes

Trost, Barry M.,Kalnmals, Christopher A.

, p. 2346 - 2349 (2017/05/12)

Herein, a ruthenium-catalyzed cycloisomerization that transforms 1,6-haloenynes into 5-membered carbo- and heterocycles that bear exocyclic, stereodefined, tetrasubstituted vinyl halides is reported. The reaction is insensitive to air and water, tolerates a variety of functional groups, and proceeds with good to excellent stereoselectivity and yield.
