77548-31-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77548-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,4 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77548-31:
(7*7)+(6*7)+(5*5)+(4*4)+(3*8)+(2*3)+(1*1)=163
163 % 10 = 3
So 77548-31-3 is a valid CAS Registry Number.

Palladium-Catalyzed Tandem γ-Arylation/Aromatization of Cyclohex-2-En-1-One Derivatives: A Route to 3,4-Dihydroanthracen-1(2H)-Ones

Feng, Chen-Guo,Fu, Jian-Guo,Lin, Guo-Qiang,Song, Yi-Kang,Xu, Si-Yu,Zhang, Shu-Sheng

supporting information, p. 3001 - 3005 (2021/05/07)

An intramolecular palladium-catalyzed tandem γ-arylation/aromatization reaction of cyclohex-2-en-1-one derivatives was developed. This work provides a simple and efficient approach for the construction of substituted 3,4-dihydroanthracen-1(2H)-ones in good yields with a broad substrate scope. (Figure presented.).

High-yielding synthesis of Nefopam analogues (functionalized benzoxazocines) by sequential one-pot cascade operations

Ramachary, Dhevalapally B.,Narayana, Vidadala V.,Prasad, M. Shiva,Ramakumar, Kinthada

body text, p. 3372 - 3378 (2010/01/06)

An efficient amine-/ruthenium-catalyzed three-step process for the synthesis of Nefopam analogues was achieved through combinations of cascade enamine amination/iso-aromatization/allylation and diene or enyne metathesis as key steps starting from functionalized Hagemann's esters. In this communication, we discovered the application of ruthenium-catalysis on olefins containing free amines without in situ formation of salts.
