680997-58-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 680997-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,0,9,9 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 680997-58:
(8*6)+(7*8)+(6*0)+(5*9)+(4*9)+(3*7)+(2*5)+(1*8)=224
224 % 10 = 4
So 680997-58-4 is a valid CAS Registry Number.

Cycloadditions of o-quinone dimethides with p-quinol derivatives: Regiocontrolled formation of anthracyclic ring systems

Wang, Junhua,Pettus, Liping H.,Pettus, Thomas R. R.

, p. 1793 - 1796 (2004)

Regioselective cycloadditions between the cyclohexadienones 12-14 and the ortho-quinone dimethide 19, which is thermally generated from the corresponding 1,3-dihydro-1-methoxy-2,2-dioxide benzo[c]thiophene 27, are reported. The synthetic sequence provides

Total synthesis of (+)-rishirilide B: Development and application of general processes for enantioselective oxidative dearomatization of resorcinol derivatives

Mejorado, Lupe H.,Pettus, Thomas R. R.

, p. 15625 - 15631 (2007/10/03)

A concise synthesis of (+)-rishirilide B (2) is described. This is the first synthesis to be reported for the (+)-enantiomer of rishirilide B (2) as found in nature. The strategy accentuates the valuable combination of a method for oquinone methide coupli

Diastereoselective dearomatization of resorcinols directed by a lactic acid tether: Unprecedented enantioselective access to p-quinols

Mejorado, Lupe H.,Hoarau, Christophe,Pettus, Thomas R. R.

, p. 1535 - 1538 (2007/10/03)

An operationally simple oxidative dearomatization of resorcinol derivatives is reported that employs an inexpensive chiral directing group. The method provides access to a variety of p-quinol derivatives in good yield and diastereoselectivity. A short red
