76161-51-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76161-51-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,1,6 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76161-51:
(7*7)+(6*6)+(5*1)+(4*6)+(3*1)+(2*5)+(1*1)=128
128 % 10 = 8
So 76161-51-8 is a valid CAS Registry Number.

Thiourea catalysis of NCS in the synthesis of β-chloroethers

Bentley, Paul A.,Mei, Yujiang,Du, Juan

, p. 2653 - 2655 (2008/09/19)

Thiourea catalysis of olefin chlorination with NCS in an alcohol gives β-chloroethers with a very fast reaction of high yield.

Three-Component Reactions. VIII. Chlorination of Olefines in N-Methylpyrrolidone

Beger, J.,Jacobi, R.,Storch, A.,Ullmann, M.

, p. 394 - 400 (2007/10/02)

The chlorination of cyclohexene, styrene and 1-dodecene in NMP gives immonium-chlorides 5 reacting with water to β-chloralkyl-γ-N-methylaminobutyrat-hydrochlorides.With cyclohexene the reaction proceeds stereospecifically as trans-addition.From styrene there is only formed the Markovnikov product, and from dodecene a mixture of isomeres is obtained containing about 30percent of the anti-Markovnikov product.
