13705-82-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13705-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,0 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13705-82:
(7*1)+(6*3)+(5*7)+(4*0)+(3*5)+(2*8)+(1*2)=93
93 % 10 = 3
So 13705-82-3 is a valid CAS Registry Number.

Oxidation of Primary and Secondary Alcohols by the Catalysis of Palladium

Tamaru, Yoshinao,Yamada, Yoshimi,Inoue, Kenji,Yamamoto, Youichi,Yoshida, Zen-ichi

, p. 1286 - 1292 (2007/10/02)

Saturated and unsaturated alcohols are oxidized to the corresponding ketones in good or excellent yields by using an aryl halide (phenyl bromide or mesityl bromide) as an oxidant and palladium(0) or -(II) as a catalyst (0.6-3 mol percent relative to the alcohol) in the presence of a base (NaH or K2CO3).The similar oxidation of primary alcohols provides the corresponding aldehydes and/or esters.The aldehyde/ester selectivity is correlated to the steric and electronic features of substrates.The procedure is applied to the oxidation of 1-primary,ω-primary diols to lactones.
