Check Digit Verification of cas no

The CAS Registry Mumber 99440-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,4 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99440-98:
(7*9)+(6*9)+(5*4)+(4*4)+(3*0)+(2*9)+(1*8)=179
179 % 10 = 9
So 99440-98-9 is a valid CAS Registry Number.

The novel di((camphorsulfonyl)oxy)iodo]benzene (DCIB) was synthesized from [Bis(trifluoroacetoxy)iodo]benzene in the mild conditions. The α-sulfonoxylation of various ketones with novel hypervalent iodine was reported in excellent yield. α-Hydroxyketones

Ligustrazine-fused cyclic compound and medicine composition thereof, as well as application in medicine thereof

-

, (2017/07/21)

The invention discloses a ligustrazine-fused cyclic compound and a medicine composition thereof and application in a medicine. The ligustrazine-fused cyclic compound has the following structural general formula I: as shown in the specification. The medicine composition is a medicinal active component for the ligustrazine-fused cyclic compound and a pharmaceutically acceptable carrier, an excipient, a diluent, an adjuvant, a medium or a combination thereof; the ligustrazine-fused cyclic compound and the medicine composition can be used for preventing or treating cardiovascular and cerebrovascular diseases, digestive system diseases, respiratory diseases, the alzheimer's disease, kidney diseases and complications of the above-mentioned diseases due to thrombus and excessive free radicals. The ligustrazine-fused cyclic compound disclosed by the invention has an extremely good inhibition effect on in vitro ADP (adenosine diphosphate)-induced platelet aggregation; meanwhile, compared with the pharmacokinetic property of ligustrazine serving as a female parent, the pharmacokinetic property of the ligustrazine-fused cyclic compound in the body of a rat is obviously improved.

An efficient method for selective oxidation of 1,2-diols in water catalyzed by Me2SnCl2

William, Julius M.,Kuriyama, Masami,Onomura, Osamu

, p. 19247 - 19250 (2013/10/22)

Dimethyltin(iv)dichloride-catalyzed selective oxidation of 1,2-diols in water was achieved using dibromoisocyanuric acid (DBI) or Br2 as oxidants. The catalyst activates the 1,2-diol moiety through the formation of stannylene acetal in addition to enhancing selectivity. Various cyclic and acyclic 1,2-diol substrates have been selectively oxidized affording α-hydroxyketones in good to excellent yields. This method is safe and simple in operation.
