90145-12-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90145-12-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,4 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90145-12:
(7*9)+(6*0)+(5*1)+(4*4)+(3*5)+(2*1)+(1*2)=103
103 % 10 = 3
So 90145-12-3 is a valid CAS Registry Number.

experimental part, p. 2989 - 2994 (2009/06/20)

Stereoselective total synthesis of α,β-unsaturated lactone (1a), isolated from Ravensara crassifolia, has been achieved efficiently starting from chiral 2,3-O-isopropylidene-d-glyceraldehyde (3) followed by asymmetric allylation and ring-closing metathesi

An azido-functionalized isocarbacyclin analogue acting as an efficient photoaffinity probe for a prostacyclin receptor

Suzuki, Masaaki,Koyano, Hiroshi,Noyori, Ryoji,Hashimoto, Hitoshi,Negishi, Manabu,Ichikawa, Atsushi,Ito, Seiji

, p. 2635 - 2658 (2007/10/02)

A stable prostacyclin analogue, (15S)-18c, having an azidophenyl group as a photoaffinity labeling functionality has been synthesized. This compound has a sufficiently high affinity to the prostacyclin receptor protein in mastocytoma P-815 cells, exhibiting an IC50 value of 3 nM for the replacement of iloprost bound to the receptor protein. A photoaffinity probe compound, [3H]-(15S)-18c, is obtainable by reduction of the ketone 16c with [3H]NaBH4 - CeCl3 followed by alkaline hydrolysis of the methyl ester.
