17275-86-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17275-86-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,7 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17275-86:
(7*1)+(6*7)+(5*2)+(4*7)+(3*5)+(2*8)+(1*6)=124
124 % 10 = 4
So 17275-86-4 is a valid CAS Registry Number.

Synthesis of Axially Chiral 2,2′-Bisphosphobiarenes via a Nickel-Catalyzed Asymmetric Ullmann Coupling: General Access to Privileged Chiral Ligands without Optical Resolution

Zuo, Ziqing,Kim, Raphael S.,Watson, Donald A.

, p. 1328 - 1333 (2021/02/01)

We report an asymmetric homocoupling of ortho-(iodo)arylphosphine oxides and ortho-(iodo)arylphosphonates resulting in highly enantioenriched axially chiral bisphosphine oxides and bisphosphonates. These products are readily converted to enantioenriched b

ENHANCING AUTOPHAGY OR INCREASING LONGEVITY BY ADMINISTRATION OF UROLITHINS OR PRECURSORS THEREOF

-

, (2014/01/17)

Disclosed are methods, compounds, and compositions useful for increasing autophagy and promoting longevity. The methods, compounds, and compositions relate to urolithins and urolithin precursors and use thereof. Certain urolithins are represented by Formula I, while certain urolithin precursors are represented by Formula IV. The urolithin may be urolithin A, urolithin B, urolithin C, or urolithin D. The urolithin precursor may be ellagic acid or an ellagitannin. The methods include in vivo, ex vivo, and in vitro uses of the compounds and compositions.

The first synthesis of C-terminal biphenyl moiety of vancomycin

Rama Rao,Chakraborty,Joshi

, p. 4045 - 4048 (2007/10/02)

A successful Palladium catalysed intramolecular coupling of phenyl rings corresponding to amino acids (R)-4-hydroxyphenylglycine and (S)-3,5-dihydroxyphenylglycine of vancomycin is achieved.
