Check Digit Verification of cas no

The CAS Registry Mumber 127758-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,5 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127758-25:
(8*1)+(7*2)+(6*7)+(5*7)+(4*5)+(3*8)+(2*2)+(1*5)=152
152 % 10 = 2
So 127758-25-2 is a valid CAS Registry Number.

Asymmetric total synthesis of two naturally occurring α,β-enone containing RALs, L-783290 and L-783277 is described in this article. An E-selective Horner-Wadsworth-Emmons (HWE) olefination was used as a key reaction to construct the C7′-C8′ olefinic unsaturation in L-783290. An enantiopure alkyne addition to the aldehyde followed by Z-selective partial reduction was employed to construct the C7′-C8′ olefinic unsaturation in L-783277. Biomimetic lactonization reaction was used to construct the macrolactone core in both the target molecules.

D-erythro-sphingosine synthesis method

-

, (2017/08/31)

The invention relates to a D-erythro-sphingosine synthesis method, comprising the steps of dissolving a compound 6 into dry tetrahydrofuran, adding lithium aluminum hydride under protection of nitrogen, after complete reaction of a raw material, adding a potassium sodium tartrate solution and finishing; extracting through ethyl acetate, concentrating and performing column chromatography; separating to obtain D-erythro-sphingosine. Compared with a traditional method, the synthesis method provided by the invention has the advantages that the use of a large amount of strong base phenyl lithium in a Wittig reaction process is avoided, meanwhile, the yield is increased; an azidation reaction adopts a two-step method of iodination and then azidation, and low temperature reaction in the existing technical scheme is not needed, so that the operation is more convenient and simple.
