175439-05-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 175439-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,4,3 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 175439-05:
(8*1)+(7*7)+(6*5)+(5*4)+(4*3)+(3*9)+(2*0)+(1*5)=151
151 % 10 = 1
So 175439-05-1 is a valid CAS Registry Number.

A new approach to the synthesis of 2-vinylthiophenes and selenophenes; competition between free radical and anionic cycloaromatization of bridged di- and tetrapropargylic sulfides and selenides

Zafrani, Yossi,Cherkinsky, Marina,Gottlieb, Hugo E.,Braverman, Samuel

, p. 2641 - 2649 (2007/10/03)

A series of unknown di- and tetrapropargylic sulfides and selenides have been prepared. In the presence of t-BuOK in dry THF these compounds underwent isomerization to the corresponding diallenes, followed by a tandem anionic cyclization and aromatization

A direct route to conjugated enediynes from dipropargylic sulfones by a modified one-flask Ramberg-Baecklund reaction

Cao, Xiaoping,Yang, Yuying,Wang, Xiaolong

, p. 2485 - 2489 (2007/10/03)

The reaction of dipropargylic sulfones with dibromodifluoromethane in the presence of alumina-supported KOH in dichloromethane solution results in facile rearrangement affording the corresponding conjugated linear and cyclic enediynes in good yields. This result shows that the direct transformation of a- and a′-hydrogen bearing sulfones assembles enediyne units without resorting to the prior preparation of the a-halo sulfone precursors in a separate step.

Direct conversion of dipropargylic sulfones into (E)- and (Z)-Hex-3-ene-1,5-diynes by a modified one-flask Ramberg-Backlund reaction

Cao,Chan,Chow

, p. 1049 - 1052 (2007/10/03)

(E)- and (Z)-enediynes 7 are readily synthesized in good yields from a one-pot modified Ramberg-Backlund reaction from dipropargylic sulfones 5.
