108521-49-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 108521-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,5,2 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 108521-49:
(8*1)+(7*0)+(6*8)+(5*5)+(4*2)+(3*1)+(2*4)+(1*9)=109
109 % 10 = 9
So 108521-49-9 is a valid CAS Registry Number.

A facile direct conversion of aldehydes to esters and amides using acetone cyanohydrin

Raj, I. Victor Paul,Sudalai

, p. 8303 - 8306 (2005)

Aromatic aldehydes with electron-withdrawing groups undergo rapid reactions with a variety of alcohols and secondary amines to afford the corresponding esters and amides, respectively, in high yields, when treated with NaCN or acetone cyanohydrin and base under ambient reaction conditions. In case of α,β-unsaturated aldehydes, simultaneous reduction of the CC bond along with esterification occurred to produce the saturated esters in high yields.

Transition-metal-free aerobic oxidative cleavage of C-C bonds in α-hydroxy ketones and mechanistic insight to the reaction pathway

Liu, Hui,Dong, Chao,Zhang, Zeguang,Wu, Peiyu,Jiang, Xuefeng

supporting information, p. 12570 - 12574 (2013/02/22)

Clear cut: For the title reaction, O2, the ideal oxidant, was used as the only oxidizing reagent. The dimer intermediate (see scheme) and isotopic labeling control experiments with 18O2 partially disclosed the reaction mec
