62338-41-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 62338-41-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,3,3 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 62338-41:
(7*6)+(6*2)+(5*3)+(4*3)+(3*8)+(2*4)+(1*1)=114
114 % 10 = 4
So 62338-41-4 is a valid CAS Registry Number.

Catalytic Access to Alkyl Bromides, Chlorides and Iodides via Visible Light-Promoted Decarboxylative Halogenation

Candish, Lisa,Standley, Eric A.,Gómez-Suárez, Adrián,Mukherjee, Satobhisha,Glorius, Frank

supporting information, p. 9971 - 9974 (2016/07/19)

Herein is reported the catalytic, visible light-promoted, decarboxylative halogenation (bromination, chlorination, and iodination) of aliphatic carboxylic acids. This operationally-simple reaction tolerates a range of functional groups, proceeds at room temperature, and is redox neutral. By employing an iridium photocatalyst in concert with a halogen atom source, the use of stoichiometric metals such as silver, mercury, thallium, and lead can be circumvented. This reaction grants access to valuable synthetic building blocks from the large pool of cheap, readily available carboxylic acids.

p-Toluenesulfonic Acid Adsorbed on Silica Gel: An Efficient Dehydrating Agent of Alcohols

D'Onofrio, Franco,Scettri, Arrigo

, p. 1159 - 1161 (2007/10/02)

Secondary and tertiary alcohols are efficiently dehydrated by reaction with p-toluenesulfonic acid supported on silica gel.In particular, the procedure allows the direct conversion of 3-hydroxy-steroids into Δ2-olefins or Δ3,5-dienes, without passing through the mesylate or tosylate esters.
