59853-64-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 59853-64-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,8,5 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 59853-64:
(7*5)+(6*9)+(5*8)+(4*5)+(3*3)+(2*6)+(1*4)=174
174 % 10 = 4
So 59853-64-4 is a valid CAS Registry Number.

K2S2O8-promoted C-Se bond formation to construct α-phenylseleno carbonyl compounds and α,β-unsaturated carbonyl compounds

Yang, Xue-Yan,Wang, Ruizhe,Wang, Lu,Li, Jianjun,Mao, Shuai,Zhang, San-Qi,Chen, Nanzheng

, p. 28902 - 28905 (2020/08/25)

A novel K2S2O8-promoted C-Se bond formation from cross-coupling under neutral conditions has been developed. A variety of aldehydes and ketones react well using K2S2O8 as the oxidant in the absence of catalyst and afford desired products in moderate to excellent yields. This protocol provides a very simple route for the synthesis of α-phenylseleno carbonyl compounds and α,β-unsaturated carbonyl compounds.
