Check Digit Verification of cas no

The CAS Registry Mumber 131729-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,2 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131729-99:
(8*1)+(7*3)+(6*1)+(5*7)+(4*2)+(3*9)+(2*9)+(1*9)=132
132 % 10 = 2
So 131729-99-2 is a valid CAS Registry Number.

Disubstituted tetrahydrofurans and dioxolanes as PAF antagonists

Bartroli,Carceller,Merlos,Garcia-Rafanell,Forn

, p. 373 - 386 (2007/10/02)

A new series of disubstituted tetrahydrofuran and dioxolane derivatives were prepared and evaluated for their PAF antagonist activity in the PAF-induced in vitro platelet-aggregation and in vivo hypotension tests. Several of these compounds exhibited more potent activity than the structurally related 2-[N-acetyl-N-[[[[2-methoxy-3-[(octadecylcarbamoyl)oxy]propoxy] carbonyl]amino]methyl]-1-ethylpyridinium chloride (CV-6209, 3) in the in vitro assay, whereas all showed less potency in the in vivo test. The role of both the substituent nature and the placement and number of oxygen atoms in the ring are discussed. A qualitative SAR study was carried out on these nuclei.
