69225-80-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69225-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,2,2 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69225-80:
(7*6)+(6*9)+(5*2)+(4*2)+(3*5)+(2*8)+(1*0)=145
145 % 10 = 5
So 69225-80-5 is a valid CAS Registry Number.

Chemo- and regioselective reductive deoxygenation of 1-en-4-yn-ols into 1,4-enynes through FeF3 and TfOH co-catalysis

Yang, Zonglian,Kumar, Rapolu Kiran,Liao, Peiqiu,Liu, Zhaohong,Li, Xingqi,Bi, Xihe

supporting information, p. 5936 - 5939 (2016/05/24)

We report chemo- and regioselective direct reductive deoxygenation of 1-en-4-yn-3-ols into 1,4-enynes through FeF3 and TfOH cooperative catalysis under NBSH-mediated conditions. Further, we show the efficient synthesis of a pharmaceutically significant 1,4-enyne. The present methodology can also be used for chemo- and regioselective direct deoxygenation of other alcohols.

Synthesis of substituted naphthalenes and carbazoles by the palladium-catalyzed annulation of internal alkynes

Huang, Qinhua,Larock, Richard C.

, p. 7342 - 7349 (2007/10/03)

An efficient synthesis of highly substituted naphthalenes has been developed by the palladium-catalyzed annulation of a variety of internal alkynes, in which two new carbon-carbon bonds are formed in a single step under relatively mild reaction conditions
