38849-38-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 38849-38-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,8,4 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 38849-38:
(7*3)+(6*8)+(5*8)+(4*4)+(3*9)+(2*3)+(1*8)=166
166 % 10 = 6
So 38849-38-6 is a valid CAS Registry Number.

First total synthesis of the pavine alkaloid (±)-neocaryachine and its optical resolution

Miura, Yuta,Saito, Yohei,Goto, Masuo,Nakagawa-Goto, Kyoko

, p. 899 - 902 (2020/11/26)

The first total synthesis of (±)-neocaryachine (1) was achieved using a radical cyclization to produce the dibenzo-9-azabicyclo[3.3.1]nonane pavine skeleton, following a Bischler-Napieralski reaction to construct an intermediate benzylisoquinoline. The resulting racemic mixture was separated by chiral column chromatography to provide pure (+)- and (?)-1.

Improved synthesis of nigricanin

Abe, Hitoshi,Nagai, Takanori,Imai, Haruka,Horino, Yoshikazu

, p. 1078 - 1080 (2017/11/17)

An ellagic acid-related natural product, nigricanin (1), was synthesized via the Ullmann coupling reaction of 2-bromo-3,4-dialkoxybenzaldehyde (4) followed by the Cannizzaro reaction for desymmetrization of the symmetric biaryl compound (5). Compared to o

With anti-tumor activity of a biphenyl amide compound and its preparation method and application

-

, (2016/11/24)

The invention discloses a biphenyl amide compound with antitumor activity as well as a preparation method and application thereof. The structural formula of the compound is shown in the specification, wherein in the structural formula, R1 is hydrogen or halogen; R2 is alkoxy with carbon number of 1-4; the terminal of R2 is replaced by tert-amido; R2 is linked to the para-position of amide via an oxygen atom. The compound has good tumor cell inhibiting activity in vitro and can be used for preparing antitumor drugs, especially anti-hepatoma drugs and anti-breast cancer drugs. The preparation method of the biphenyl amide compound, provided by the invention, has the advantages that the raw materials are accessible, the reaction conditions are mild, the reaction process is simple to operate, and the used reagent is cheap.
