Check Digit Verification of cas no

The CAS Registry Mumber 119967-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,6 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119967-39:
(8*1)+(7*1)+(6*9)+(5*9)+(4*6)+(3*7)+(2*3)+(1*9)=174
174 % 10 = 4
So 119967-39-4 is a valid CAS Registry Number.

TMDS-Pd/C: A convenient system for the reduction of acetals to ethers

Shi, Yan,Dayoub, Wissam,Chen, Guo-Rong,Lemaire, Marc

, p. 1281 - 1283 (2011)

A simple and practical procedure for the reduction of acetals to ethers is described. It is based on the use of a 1,1,3,3-tetramethyldisiloxane (TMDS)-Pd/C system in the presence of a Br?nsted acid as the co-catalyst. The reaction occurs under mild conditions and ethers are obtained in high yields.

Ethoxylation of aralkyl alcohols

Huszar, Klara Parlagh,Klug, Otto,Parlagh, Gyula,Rusznak, Istvan,Sallay, Peter,et al.

, p. 241 - 252 (2007/10/03)

An important reaction, the oligoaddition of ethylene oxide to the alcoholic hydroxyl group was investigated.The aralkyl alcohols were chosen as base material: benzyl-, β-phenylethyl- and γ-phenylpropyl alcohols.The first members of their homologue ethoxylated series were prepared and used as standards for the determination of the average degree of ethoxylation (IR, UV, refractive indices) and of the molar mass distribution (HPLC).

The Distribution of Compounds Formed in the Reaction between Ethylene Oxide and Alcohols

Weibull, Bengt

, p. 207 - 216 (2007/10/02)

In the reaction between ethylene oxide and an alcohol in the presence of a small amount of the alkoxide, a mixture of monoalkyl ethers of oligoethylene glycols is formed.The distribution of these homologous ethers was studied with 3-phenylpropan-1-ol as t
