221699-65-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 221699-65-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,6,9 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 221699-65:
(8*2)+(7*2)+(6*1)+(5*6)+(4*9)+(3*9)+(2*6)+(1*5)=146
146 % 10 = 6
So 221699-65-6 is a valid CAS Registry Number.

Stereochemical course of the hydrogen migration in the boron trifluoride etherate-catalyzed rearrangement of 1,1-disubstituted epoxides

Hara, Noriyuki,Mochizuki, Akiyoshi,Tatara, Akinori,Fujimoto, Yoshinori

, p. 1859 - 1868 (2000)

Mechanistic studies on the BF3.Et2O-catalyzed rearrangement of optically active, regioselectively deuterated 1,1-disubstituted epoxides to aldehydic products revealed that the two hydrogens migrate at the migration terminus with oppo

Biarylphosphonite gold(I) complexes as superior catalysts for oxidative cyclization of propynyl arenes into indan-2-ones

Henrion, Guilhem,Chavas, Thomas E. J.,Le Goff, Xavier,Gagosz, Fabien

supporting information, p. 6277 - 6282 (2013/07/11)

Striking gold: A series of variously functionalized propynyl arenes was smoothly converted into indan-2-ones by a new gold(I)-catalyzed oxidative cyclization process. [LAu]NTf2 (Tf=trifluoromethanesulfonyl) is a superior catalyst both in terms of yield and kinetics for the present transformation. Copyright
