91875-49-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91875-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,7 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91875-49:
(7*9)+(6*1)+(5*8)+(4*7)+(3*5)+(2*4)+(1*9)=169
169 % 10 = 9
So 91875-49-9 is a valid CAS Registry Number.

I2-Catalyzed C-O Bond Formation and Dehydrogenation: Facile Synthesis of Oxazolines and Oxazoles Controlled by Bases

Gao, Wen-Chao,Hu, Fei,Huo, Yu-Ming,Chang, Hong-Hong,Li, Xing,Wei, Wen-Long

supporting information, p. 3914 - 3917 (2015/08/18)

A general method for the synthesis of oxazolines and oxazoles was developed through I2-catalyzed C-O bond formation and dehydrogenation with the same oxidant, TBHP. By simply tuning reaction bases, either oxazolines or oxazoles were selectively
