67341-33-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67341-33-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,3,4 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67341-33:
(7*6)+(6*7)+(5*3)+(4*4)+(3*1)+(2*3)+(1*3)=127
127 % 10 = 7
So 67341-33-7 is a valid CAS Registry Number.

A simple, efficient and regioselective oxychlorination of aromatic compounds using ammonium chloride and oxone

Narender,Mohan, K.V.V. Krishna,Srinivasu,Kulkarni,Raghavan

, p. 1335 - 1338 (2007/10/03)

A simple, efficient, mild and regioselective method for oxychlorination of aromatic compounds is reported. The electrophilic substitution of chlorine generated in situ from NH4Cl as a chlorine source and oxone as an oxidant is reported for the first time.

Formation of Nonaromatic Products in the Chlorination of Simple Substituted Aromatic Ethers

Watson, William David

, p. 5270 - 5276 (2007/10/02)

The neat chlorination of 4-chloroanisole produces 1,3,4,5,6-pentachloro-4-methoxycyclohexene in 35percent yield.Mono- and dichlorinated anisoles and a variety of simple substituted anisoles were chlorinated to determine the generality of nonaromatic product formation. 3,4-Dichloroanisole, 4-fluoroanisole, 4-bromoanisole, 4-methylanisole, and 4-chlorophenetole form similar products based on their spectral properties.These products are proposed to form by a cis-1,2-chlorine addition followed by rapid cis-1,4 chlorine addition.On the basis of the NMR data, a predominate configuration is proposed.
