Check Digit Verification of cas no

The CAS Registry Mumber 27383-89-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,3,8 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27383-89:
(7*2)+(6*7)+(5*3)+(4*8)+(3*3)+(2*8)+(1*9)=137
137 % 10 = 7
So 27383-89-7 is a valid CAS Registry Number.

Copper-catalyzed oxidative cyclization of glycine derivatives toward 2-substituted benzoxazoles

Liu, Shan,Zhu, Zhi-Qiang,Hu, Zhi-Yu,Tang, Juan,Yuan, En

, p. 1616 - 1619 (2021)

A novel and straightforward intramolecular cyclization of glycine derivatives to 2-substituted benzoxazoles through copper-catalyzed oxidative C-H/O-H cross-coupling was described. A variety of glycine derivatives involving short peptides underwent cross-dehydrogenative-coupling readily to afford diverse 2-substituted benzoxazoles. The synthetic method has the advantages of simple operation, broad substrate scope and mild reaction conditions, thus providing an alternative effective approach for benzoxazole construction.
