Check Digit Verification of cas no

The CAS Registry Mumber 206554-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,5,5 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 206554-22:
(8*2)+(7*0)+(6*6)+(5*5)+(4*5)+(3*4)+(2*2)+(1*2)=115
115 % 10 = 5
So 206554-22-5 is a valid CAS Registry Number.

METHOD OF PRODUCING ALDEHYDE COMPOUND OR KETONE COMPOUND

-

Paragraph 0204-0207; 0208; 0212-0220; 0222, (2018/08/30)

A method of producing an aldehyde compound or a ketone compound by oxidation of a primary or secondary alcohol compound having, in the molecule, a group selected from an amino group, an azido group, a hydroxy group, and a hydroxy group protected with a protective group, the method containing the steps of: a first step including colliding and mixing the alcohol compound, a dialkyl sulfoxide having 2 to 8 carbon atoms, and an acid anhydride having 4 to 10 carbon atoms in a flow-through type reactor to cause a reaction; anda second step including colliding and mixing, in a flow-through type reactor, a trialkylamine having 3 to 10 carbon atoms and the mixture liquid obtained in the first step to cause a reaction; wherein the reactions in the first step and the second step are sequentially performed.

Synthesis of enantiopure diamine ligands related to sparteine, via scandium triflate-catalyzed imino Diels-Alder reactions

Danieli, Bruno,Lesma, Giordano,Passarella, Daniele,Piacenti, Paola,Sacchetti, Alessandro,Silvani, Alessandra,Virdis, Andrea

, p. 7155 - 7158 (2007/10/03)

Imino Diels-Alder reactions have been investigated as a new route to sparteine analogues. The first enantioselective synthesis of two diastereoisomeric tricyclic diamines, structurally equivalent to the ABC and BCD rings of the naturally occurring alkaloid, is reported, starting from enantiopure intermediates. The effectiveness of the diamines in the lithiation of N-Boc-pyrrolidine is discussed.
