Check Digit Verification of cas no

The CAS Registry Mumber 352311-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,3,1 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 352311-22:
(8*3)+(7*5)+(6*2)+(5*3)+(4*1)+(3*1)+(2*2)+(1*2)=99
99 % 10 = 9
So 352311-22-9 is a valid CAS Registry Number.

Enamide-benzyne-[2 + 2] cycloaddition: Stereoselective tandem [2 + 2]-pericyclic ring-opening-intramolecular N-tethered [4 + 2] cycloadditions

Feltenberger, John B.,Hayashi, Ryuji,Tang, Yu,Babiash, Eric S.C.,Hsung, Richard P.

supporting information; experimental part, p. 3666 - 3669 (2011/02/25)

Image Presented Benzyne-[2 + 2] cycloadditions with enamides are described. This effort led to the development of a highly stereoselective tandem [2 + 2] cycloaddition-pericyclic ring-opening-intramolecular-N-tethered-[4 + 2] cycloaddition for rapid assembly of nitrogen heterocycles.

Enamide-Olefin Ring-Closing Metathesis

Kinderman, Sape S.,Van Maarseveen, Jan H.,Schoemaker, Hans E.,Hiemstra, Henk,Rutjes, Floris P. J. T.

, p. 2045 - 2047 (2007/10/03)

(matrix presented) The first examples of ring-closing metathesis reactions of olefin-containing enamides using ruthenium-based catalysts have been demonstrated. A preliminary investigation into the scope and limitations, leading to protected five- and six-membered cyclic enamides, will be presented.
