503130-84-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 503130-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,1,3 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 503130-84:
(8*5)+(7*0)+(6*3)+(5*1)+(4*3)+(3*0)+(2*8)+(1*4)=95
95 % 10 = 5
So 503130-84-5 is a valid CAS Registry Number.

Concise synthesis of cyclic carbonyl compounds from haloarenes using phenyl formate as the carbonyl source

Konishi, Hideyuki,Nagase, Hiroki,Manabe, Kei

supporting information, p. 1854 - 1857 (2015/01/30)

Various cyclic carbonyl compounds were concisely synthesized by carbonylative cyclization of haloarenes bearing nucleophilic moieties under Pd catalysis. A broad substrate scope and a feasible large-scale synthesis clearly demonstrate the high applicability of the reaction as a general, user-friendly method for access to cyclic carbonyl compounds.

Design and synthesis of 1-benzazepine derivatives by strategic utilization of Suzuki-Miyaura cross-coupling, aza-Claisen rearrangement and ring-closing metathesis

Kotha, Sambasivarao,Shah, Vrajesh R.

scheme or table, p. 1054 - 1064 (2009/04/05)

A new and simple methodology has been realized for the synthesis of 7-substituted 2,3,4,5-tetrahydro-1-benzazepine derivatives with Suzuki-Miyaura cross-coupling, aza-Claisen rearrangement and ring-closing metathesis (RCM) the key steps. Here, o-allylacet
