Check Digit Verification of cas no

The CAS Registry Mumber 185225-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,2,2 and 5 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 185225-06:
(8*1)+(7*8)+(6*5)+(5*2)+(4*2)+(3*5)+(2*0)+(1*6)=133
133 % 10 = 3
So 185225-06-3 is a valid CAS Registry Number.

The invention provides a preparation method of a carboprost tromethamine intermediate. The method comprises the following steps: A) carrying out an oxidation reaction on benzoyl corey lactone alcohol shown in a formula I under the action of a catalyst and an oxidizing agent to obtain benzoyl corey lactone aldehyde shown in a formula II; B) reacting the benzoyl corey lactone aldehyde as shown in the formula II with dimethyl (2-oxoheptyl) phosphonate under the action of alkali to obtain a 15-ketone crude product as shown in a formula III, and recrystallizing the 15-ketone crude product to obtain a 15-ketone pure product; and C) carrying out methylation reaction on the 15-ketone pure product to obtain the carboprost tromethamine intermediate as shown in a formula IV. According to the invention, the use of reagents with high toxicity and serious environmental pollution is avoided; when the carboprost intermediate 15-ketone is prepared, a mixed solvent is adopted for recrystallization, so that column chromatography is omitted, operation is easy and convenient, reagents are saved, and cost is reduced; and in the methylate preparation process, ultralow temperature is avoided, and the reaction time is shortened, so that the energy consumption is reduced, and the purity and the yield are relatively high.

Enantio- and stereospecific syntheses of 15(R)-Me-PGD2, a potent and selective DP2-receptor agonist

supporting information; scheme or table, p. 7213 - 7218 (2009/05/26)

(Chemical Equation Presented) The first total synthesis of 15(R)-Me-PGD2 3 is reported. The synthesis is based on the enantioselective and stereospecific syntheses of synthon 17 and its attachment to the five-membered ring by a olefin cross metathesis reaction. This approach permits the introduction of a side chain with a predetermined stereogenic center into the prostanoid ring, resulting in the synthesis of 15R-methyl prostaglandin D2 and allows rapid access to other prostanoids.

The first total synthesis of 15R-PGD2 3 was accomplished. The approach used in this report is also an efficient method to produce 15R-PGE 2. 15R-PGD2, a potential DP2 receptor agonist, could be an important novel tool for defining the role of this receptor in inflammatory diseases.

The Aldol Reaction of Substituted Cyclopentane Carbaldehydes with 2-Heptanone. A Novel Approach to the Construction of the Alkyl Side Chain of Prostaglandins

Mahrwald, Rainer,Schick, Hans,Schwarz, Sigfrid

, p. 385 - 390 (2007/10/02)

The aldol reaction of suitably substituted cyclopentane carbaldehydes (1a-c, 4) with 2-heptanone affords β-hydroxy ketones (2a-c, 5) in yields up to 60percent.These aldolization products can be dehydrated to known prostaglandin intermediates.Due to the difficulty to convert β,δ-dihydroxy ketones selectively into α,β-unsaturated δ-hydroxy ketones this reaction sequence for the construction of the (E)-3-oxooct-1-enyl side chain of prostaglandins seems to be especially advantageous for the synthesis of 11-deoxy-prostaglandins.
