867203-96-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 867203-96-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,7,2,0 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 867203-96:
(8*8)+(7*6)+(6*7)+(5*2)+(4*0)+(3*3)+(2*9)+(1*6)=191
191 % 10 = 1
So 867203-96-1 is a valid CAS Registry Number.

Preparation of isoxazol(in)yl substituted selenides and their further deselenenylation reaction to synthesize 3,5-disubstituted isoxazoles

Xu, Wei Ming,Tang,Huang, Xian

, p. 501 - 506 (2005)

We report a mild 1,3-dipolar cycloaddition protocol for the preparation of 3-aryl-5-phenylselenomethyl isoxazoles and isoxazolines regioselectively. The former was further reacted with LDA and electrophilic substrates followed by selenoxide syn-eliminatio

A novel cleavage for polystyrene-supported selenium resins: An efficient route to 3,5-disubstituted isoxazolines and their derivatives

Xu, Wei-Ming,Wang, Yu-Guang,Miao, Mao-Zhong,Huang, Xian

, p. 2143 - 2146 (2007/10/03)

We report here a novel cleavage method for polystyrene-supported selenium resin using CH3I-NaI under mild conditions to prepare 3,5-disubstituted isoxazolines. The polymer selenium resins can be reused without further transformation. Georg Thie
