473-29-0 Usage
General Description
Dichloramine B, also known as NHCl2, is a chemical compound comprised of nitrogen, hydrogen, and chlorine. Through hydrolysis and disproportionation, it is produced in small quantities when ammonia and chlorine are combined. It occurs as an intermediate step in the process of producing monochloramine and nitrogen trichloride. The substance is a prominent component in public water system disinfection often found in chloraminated water. However, due to its unstable and transient nature, direct detection of Dichloramine B is challenging, which makes its influence on water quality somewhat uncertain. Additionally, it can potentially contribute to the formation of harmful disinfection byproducts.
Check Digit Verification of cas no
The CAS Registry Mumber 473-29-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 473-29:
(5*4)+(4*7)+(3*3)+(2*2)+(1*9)=70
70 % 10 = 0
So 473-29-0 is a valid CAS Registry Number.

Copper-promoted iodovinylation of amides: synthesis of β-functionalized enamides
Sanapo, Gabriel F.,Daoust, Benoit
, p. 4196 - 4199 (2008/09/20)
We studied the addition of nitrogen radicals to ynol ethers in order to form β-functionalized enamides. Poor yields are reported. On the other hand, we observed that copper coupling between 1,2-diiodoethene and various amides leads to β-functionalized enamides in high yields with complete stereocontrol.
