23211-39-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23211-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,2,1 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 23211-39:
(7*2)+(6*3)+(5*2)+(4*1)+(3*1)+(2*3)+(1*9)=64
64 % 10 = 4
So 23211-39-4 is a valid CAS Registry Number.

Organocatalysis as a safe practical method for the stereospecific dibromination of unsaturated compounds

Hernandez-Torres, Gloria,Tan, Bin,Barbas, Carlos F.

supporting information; experimental part, p. 1858 - 1861 (2012/06/18)

Organocatalytic stereospecific dibromination of a wide variety of functionalized alkenes was achieved using a stable, inexpensive halogen source, 1,3-dibromo 5,5-dimethylhydantoin, and a simple thiourea catalyst at room temperature. The presence of a tertiary amine enhanced the rate of the dibromination reaction, and yields were good in various solvents, including aqueous solvents. The procedure was extended to alkynes and aromatic rings and to dichlorination reactions by using the 1,3-dichloro hydantoin derivative.

Poly(vinylpyrrolidone)-bromine complex; a mild and efficient reagent for selective bromination of alkenes and oxidation of alcohols

Lakouraj, Moslem Mansour,Tajbakhsh, Mahmood,Mokhtary, Masoud

, p. 481 - 483 (2007/10/03)

Poly(vinylpyrrolidone)-bromine complex (PVP-Br2) is easily prepared and used as a mild and convenient reagent for selective bromination of alkenes and at the position α-hydrogen of active carbonyl compounds. Selective oxidation of benzylic alcohols in the presence of aliphatic alcohols were also achieved at room temperature.
