756898-49-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 756898-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,6,8,9 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 756898-49:
(8*7)+(7*5)+(6*6)+(5*8)+(4*9)+(3*8)+(2*4)+(1*9)=244
244 % 10 = 4
So 756898-49-4 is a valid CAS Registry Number.

On the mechanism of the puzzling "endocyclic" skeletal rearrangement of 1,6-enynes

Cabello, Noemi,Jimenez-Nunez, Eloisa,Bunuel, Elena,Cardenas, Diego J.,Echavarren, Antonio M.

, p. 4217 - 4223 (2007)

Skeletal rearrangements of simple 1,6-enynes have been studied in order to determine the factors that control the formation of five- or six-membered rings. Simple 1,6-enynes substituted only at C-4 preferentially give six-membered rings on skeletal rearra

Tandem cyclopropanation/ring-closing metathesis of dienynes

Peppers, Brian P.,Diver, Steven T.

, p. 9524 - 9525 (2004)

Certain dienynes give cyclorearrangement by tandem cyclopropanation/ring-closing alkene metathesis, triggered by either a ruthenium carbene or noncarbene ruthenium(II) precatalyst. The process represents a variation of enyne metathesis where presumed cycl
