921198-94-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 921198-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,1,1,9 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 921198-94:
(8*9)+(7*2)+(6*1)+(5*1)+(4*9)+(3*8)+(2*9)+(1*4)=179
179 % 10 = 9
So 921198-94-9 is a valid CAS Registry Number.

Catalytic, asymmetric inverse electron demand hetero diels-alder reactions of o-benzoquinone derivatives and ketene enolates

Paull, Daniel H.,Wolfer, Jamison,Grebinski, James W.,Weatherwax, Anthony,Lectka, Thomas

, p. 240 - 246 (2008/02/09)

We present an array of [4+2] cycloaddition reactions between ketene enolates, catalytically derived from acid chlorides and cinchona alkaloid nucleophilic catalysts in the presence of stoichiometric base, and o-benzoquinone derivatives. These cycloadditio

Catalytic, asymmetric synthesis of 1,4-benzoxazinones: A remarkably enantioselective route to α-amino acid derivatives from o-benzoquinone imides

Wolfer, Jamison,Bekele, Tefsit,Abraham, Ciby J.,Dogo-Isonagie, Cajetan,Lectka, Thomas

, p. 7398 - 7400 (2008/01/27)

(Chemical Equation Presented) Cycloaddition of o-benzoquinone imides with chiral ketene enolates derived from cinchona alkaloid catalysts is the basis of a catalytic asymmetric synthesis of 1,4-benzoxazinones and 1,4-benzoxazines. The resulting cycloadduc
