Check Digit Verification of cas no

The CAS Registry Mumber 160695-09-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,6,9 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 160695-09:
(8*1)+(7*6)+(6*0)+(5*6)+(4*9)+(3*5)+(2*0)+(1*9)=140
140 % 10 = 0
So 160695-09-0 is a valid CAS Registry Number.

Synthesis and antibacterial activity of a novel series of acylides: 3-O-(3-pyridyl)acetylerythromycin A derivatives

Tanikawa, Tetsuya,Asaka, Toshifumi,Kashimura, Masato,Suzuki, Keiko,Sugiyama, Hiroyuki,Sato, Masakazu,Kameo, Kazuya,Morimoto, Shigeo,Nishida, Atsushi

, p. 2706 - 2715 (2007/10/03)

A novel series of acylides, 3-O-(aryl)acetylerythromycin A derivatives, were synthesized and evaluated. These compounds have significant potent antibacterial activity against not only Gram-positive pathogens, including inducibly macrolide-lincosamide-stre

Enantiopure building blocks for marine natural products via differentiation of enantiotopic groups

Beil, Winfried,Jones, Peter G.,Nerenz, Frank,Winterfeldt, Ekkehard

, p. 7273 - 7292 (2007/10/03)

The group and face-selective cycloaddition of the enantiopure cyclopentadiene 4 to the tyrosine-related spirocylohexadienone 10 provided a high yield of the enantiomencally pure cyclohexadienone 11. Stereoselective transformations at the remaining double bond followed by a thermal retro- process, finally giving rise to the chromophore of the marine agelorin antibiotics isolated from the sponge Agelas oroides Schmidt.

A predictable enantioselective total synthesis of (+)-clavularin A

Weinmann,Winterfeldt

, p. 1097 - 1101 (2007/10/02)

Cycloadduct 9 was transformed into vinylsilane 11d in a conjugate addition-alkylation sequence. Epoxidation and subsequent hydrolysis provided the clavularin adduct 14, which on flash vacuum pyrolysis (FVP) gave (+)-clavularin A (1) in 91% yield.
