118554-59-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118554-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,5,5 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118554-59:
(8*1)+(7*1)+(6*8)+(5*5)+(4*5)+(3*4)+(2*5)+(1*9)=139
139 % 10 = 9
So 118554-59-9 is a valid CAS Registry Number.

Cu-catalyzed intramolecular aryl-etherification reactions of alkoxyl alkynes with diaryliodonium salts via cleavage of a stable C-O bond

Chen, Jing,Chen, Chao,Chen, Junjie,Wang, Guohua,Qu, Hongmei

, p. 1356 - 1359 (2015)

A novel Cu-catalyzed intramolecular aryl-etherification reaction of alkoxyl alkynes with diaryliodonium salts is realized. The reactions proceed smoothly to produce valuable oxo-heterocycles with readily available linear starting materials via cleavage of a stable C-O bond. This journal is

Rh(iii)-Catalyzed olefination to build diverse oxazole derivatives from functional alkynes

He, Yuan,Zheng, Ting,Huang, Yin-Hui,Dong, Lin

supporting information, p. 4937 - 4942 (2021/06/16)

A novel Rh(iii)-catalyzed olefination reaction of oxazoles to generate diverse oxazole skeleton derivatives has been realized by directly using oxazole as the directing group. The reaction could tolerate many functional groups, affording complex oxazole derivatives with long chain alkenyls in moderate to good yields, which might find applications in the construction of diverse compounds.
