904848-89-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 904848-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,8,4 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 904848-89:
(8*9)+(7*0)+(6*4)+(5*8)+(4*4)+(3*8)+(2*8)+(1*9)=201
201 % 10 = 1
So 904848-89-1 is a valid CAS Registry Number.

Isolation and syn elimination of a peterson adduct to obtain optically pure product in the diastereoselective synthesis of oxazolidinone-functionalized enecarbamates

Solomon, Marissa R.,Saito, Hideaki,Sivaguru,Jockusch, Steffen,Inoue, Yoshihisa,Adam, Waldemar,Turro, Nicholas J.

body text, p. 362 - 366 (2010/04/23)

The Peterson reaction of (4R)-N-(trimethylsilyl)methyl-4-alkyloxazolidin-2- one gives (E/Z)-(4R)-N-(2', 3'- diphenylbut-1'-enyl)-4-alkyloxazolidin-2-ones (enecarbamates) with increasing (Z)-selectivity and moderate-to-high diastereoselectivity in the indi

Highly diastereoselective dioxetane formation in the photooxygenation of enecarbamates with an oxazolidinone chiral auxiliary: Steric control in the [2 + 2] cycloaddition of singlet oxygen through conformational alignment

Adam, Waldemar,Bosio, Sara G.,Turro, Nicholas J.

, p. 8814 - 8815 (2007/10/03)

The photooxygenation of oxazolidinone-substituted enecarbamates leads to diastereomerically pure dioxetanes. The high diastereoselectivity is rationalized in terms of effective π-facial control achieved by shielding one side of the double bond with the ch
