Check Digit Verification of cas no

The CAS Registry Mumber 113428-13-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,2 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113428-13:
(8*1)+(7*1)+(6*3)+(5*4)+(4*2)+(3*8)+(2*1)+(1*3)=90
90 % 10 = 0
So 113428-13-0 is a valid CAS Registry Number.

Highly Stereocontrolled Total Synthesis of Leukotriene B4, 20-Hydroxyleukotriene B4, Leukotriene B3, and Their Analogues

Kobayashi, Yuichi,Shimazaki, Toshiyuki,Taguchi, Hideki,Sato, Fumie

, p. 5324 - 5335 (2007/10/02)

A highly stereocontrolled and practical new method for synthesis of LTB4 (1), 20-OH-LTB4 (2), and LTB3 (3) has been developed, which uses the palladium catalyzed coupling reaction of the vinylborane 5, derived from the C(1)-C(9) fragment 4, with the corresponding C(10)-C(20) fragments 6a-c.The acetylene 4 was synthesized by palladium-copper-catalyzed coupling reaction of (trimethylsilyl)acetylene with the bromide 12, which was prepared from γ-(trimethylsilyl)allylic alcohol (S)-10 by bromination followed by debromosilylation.The alcohol (S)-10 was obtained by the kinetic resolution of the racemate dl-10 using the Sharpless reagent.The vinyl iodides 6a and 6b were prepared from racemic γ-(trimethylsilyl)allylic alcohols dl-17 and dl-28, respectively, by the Sharpless kinetic resolution followed by the reactions taking advantage of the reactivity of vinylsilane moiety, while the segment 6c was prepared by the Sharpless kinetic resolution of racemic γ-iodoallylic alcohol dl-34 followed by protection.By using this method, precursors of the radiolabeled LTB4, and 20-OH-LTB4, i.e., 14,15-didehydro-LTB4 (40) and 14,15-didehydro-20-OH-LTB4 (41), respectively, were also synthesized.Similarly the novel structural analogue of LTB 42-44 were prepared.

A HIGHLY EFFICIENT KINETIC RESOLUTION OF γ- AND β-TRIMETHYLSILYL SECONDARY ALLYLIC ALCOHOLS BY THE SHARPLESS ASYMMETRIC EPOXIDATION

Kitano, Yasunori,Matsumoto, Takashi,Sato, Fumie

, p. 4073 - 4086 (2007/10/02)

Kinetic resolution of γ- and β-trimethylsilyl secondary allylic alcohols proceeds with very large and synthetically satisfactory rate differences for the two enentiomers, respectively, thus providing a convenient and widely applicable method for preparati

A HIGHLY EFFICIENT SYNTHESIS OF γ-HALO ALLYLIC ALCOHOLS AND PROPARGYLIC ALCOHOLS WITH OPTICAL PURITY. PRACTICAL METHOD FOR SYNTHESIS OF THE PROSTAGLANDIN ω-CHAIN.

Okamoto, Sentaro,Shimazaki, Toshiyuki,Kobayashi, Yuichi,Sato, Fumie

, p. 2033 - 2036 (2007/10/02)

Kinetic resolution of γ-trimethylsilyl allylic alcohols 5 by the Sharpless process combined with the reactivity of epoxysilyl or vinylsilyl compounds affords a highly efficient method for preparation of optically pure γ-halo secondary allylic alcohols of type 1-4 and propargylic alcohols 14, thus providing a practical route to the prostaglandin ω-chain.
