169566-46-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 169566-46-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,5,6 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 169566-46:
(8*1)+(7*6)+(6*9)+(5*5)+(4*6)+(3*6)+(2*4)+(1*6)=185
185 % 10 = 5
So 169566-46-5 is a valid CAS Registry Number.

First synthesis of saponarin, 6-C- and 7-O-di-β-D-glucosylapigenin

Misawa, Kazufumi,Takahashi, Yasuko,Sato, Shingo

, p. 776 - 780 (2013)

Saponarin, apigenin 6-C- and 7-O-bis-β-D-glucoside, was synthesized in an overall yield of 37% via 11 steps, which included the C-glycosylation of 2,4-O-dibenzylphloroacetophenone, the introduction of a cinnamoyl residue by aldol condensation, the formati

Exploiting the therapeutic potential of 8-β- d -glucopyranosylgenistein: Synthesis, antidiabetic activity, and molecular interaction with islet amyloid polypeptide and amyloid β-peptide (1-42)

Jesus, Ana R.,Dias, Catarina,Matos, Ana M.,De Almeida, Rodrigo F.M.,Viana, Ana S.,Marcelo, Filipa,Ribeiro, Rogério T.,Macedo, Maria P.,Airoldi, Cristina,Nicotra, Francesco,Martins, Alice,Cabrita, Eurico J.,Jiménez-Barbero, Jesús,Rauter, Amélia P.

, p. 9463 - 9472 (2015/02/02)

8-β-d-Glucopyranosylgenistein (1), the major component of Genista tenera, was synthesized and showed an extensive therapeutical impact in the treatment of STZ-induced diabetic rats, producing normalization of fasting hyperglycemia and amelioration of exce

Concise synthesis of chafurosides A and B

Furuta, Takumi,Nakayama, Miho,Suzuki, Hirotaka,Tajimi, Hiroko,Inai, Makoto,Nukaya, Haruo,Wakimoto, Toshiyuki,Kan, Toshiyuki

supporting information; experimental part, p. 2233 - 2236 (2009/10/02)

The regioselective synthesis of chafurosides A (1) and B (2) from the same methyl ketone 5 was accomplished using a novel protecting group strategy. Both flavone rings were constructed from β-diketone intermediate 4, which was readily obtained by condensation of an acyl donor and ketone 5. Construction of the dihydrofuran ring was achieved via an intramolecular Mitsunobu reaction.
