Check Digit Verification of cas no

The CAS Registry Mumber 1582221-78-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,2,2,2 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1582221-78:
(9*1)+(8*5)+(7*8)+(6*2)+(5*2)+(4*2)+(3*1)+(2*7)+(1*8)=160
160 % 10 = 0
So 1582221-78-0 is a valid CAS Registry Number.

Effective C5-Arylation of Peptide-Integrated Oxazoles: Almazole D

Oberheide, Ansgar,Arndt, Hans-Dieter

, p. 1132 - 1136 (2020/12/22)

An efficient functionalization approach of oxazoles by using Pd-catalyzed cross-coupling reactions is reported. Oxazolone formation and subsequent sulfamoylation in situ are facilitated by employing N,N-diethylsulfamoyl imidazolium triflate. Cross-couplings provide both oxazole-arenes and oxazole-heteroarenes and were compatible with sensitive and epimerization-prone substrates, as exemplified by the total synthesis of the natural product almazole D. (Figure presented.).

Regioselective synthesis of oxazole derivatives via palladium-catalyzed and copper-mediated cascade oxidative cyclization

Zheng, Jia,Zhang, Min,Huang, Liangbin,Hu, Xiaohan,Wu, Wanqing,Huang, Huawen,Jiang, Huangfeng

supporting information, p. 3609 - 3611 (2014/04/03)

A novel Pd-catalyzed/Cu-mediated oxidative cyclization has been developed for the synthesis of trisubstituted oxazoles, which is thought to proceed through cascade formation of C-N and C-O bonds. In this protocol, four hydrogen atoms were removed and water was used as the oxygen atom source. This journal is the Partner Organisations 2014.
