1199-21-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1199-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1199-21:
(6*1)+(5*1)+(4*9)+(3*9)+(2*2)+(1*1)=79
79 % 10 = 9
So 1199-21-9 is a valid CAS Registry Number.

Copper Nitrate Mediated Regio- and Stereoselective Difunctionalization of Alkynes: A Direct Approach to α-Chloro-β-nitroolefins

Gao, Mingchun,Xu, Bin

, p. 4746 - 4749 (2016)

An efficient copper nitrate mediated chloronitration reaction was developed for the direct synthesis of α-chloro-β-nitroolefins with high regio- and stereoselectivity from simple alkynes and low toxic stannous chloride. This protocol provides a direct access to polysubstituted alkenes with operational simplicity, good functional group tolerance, and a wide substrate scope. Various applications of given products allowed the straightforward assembly of molecular complexity and indicated them as promising and valuable building blocks in organic synthesis.
