117901-60-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 117901-60-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,0 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 117901-60:
(8*1)+(7*1)+(6*7)+(5*9)+(4*0)+(3*1)+(2*6)+(1*0)=117
117 % 10 = 7
So 117901-60-7 is a valid CAS Registry Number.

Catalytic asymmetric claisen rearrangement of gosteli-type allyl vinyl ethers: Total synthesis of (-)-9,10-dihydroecklonialactone B

Becker, Julia,Butt, Lena,Von Kiedrowski, Valeska,Mischler, Elisabeth,Quentin, Florian,Hiersemann, Martin

supporting information, p. 3040 - 3051 (2014/05/06)

The enantioselective synthesis of (-)-9,10-dihydroecklonialactone B is described. The catalytic asymmetric Claisen rearrangement of a Gosteli-type allyl vinyl ether was utilized to afford an acyclic α-keto ester building block endowed with functionality a

A CONVENIENT APPROACH TO THE N-SUBSTITUTED AMINO DIENES, N-BENZYL-5-ETHENYL-3,4-DIHYDROPYRIDIN-2-ONE AND N-CBZ-5-ETHENYL-1,2,3,4-TETRAHYDROPYRIDINE

Bigogno, Chiara,Danieli, Bruno,Lesma, Giordano,Passarella, Daniele

, p. 973 - 982 (2007/10/02)

A synthesis of N-substituted amino dienes (1a) and (1b) is described according to two different approaches. 1a is obtained trough condensation of methyl 4-formyl-6-selenophenylhexanoate (4) with benzylamine followed by oxidation and elimination; 1b is for

Intramolecular SH2 macrocyclisations

Baldwin, Jack E.,Adlington, Robert M.,Mitchell, Mark B.,Robertson, Jeremy

, p. 5901 - 5918 (2007/10/02)

The synthesis of 10-15 membered α-methylene macrocyclic lactones from the functionalised allylstannanes (7e)-(7j) is described. Attempts to synthesise analogous 6-9 membered lactones proved unsuccessful, resulting instead in the production of dilactones and AIBN derived adducts.
