Check Digit Verification of cas no

The CAS Registry Mumber 124503-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,5,0 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 124503-05:
(8*1)+(7*2)+(6*4)+(5*5)+(4*0)+(3*3)+(2*0)+(1*5)=85
85 % 10 = 5
So 124503-05-5 is a valid CAS Registry Number.

Synthesis and properties of four-membered phosphorus heterocycles-2-Fluoro-1,2λ5-Oxaphosphetanes

Kolodiazhna, Anastasia O.,Kolodiazhnyi, Oleg I.

, p. 2232 - 2245 (2015)

(Graphical Abstract) The preparation of four-membered phosphorus(V)-heterocycles, 2-fluoro-1,2λ5-oxaphosphetanes, by reaction of P-fluoroylides with carbonyl compounds is described. The reaction is stereoselective and leads preferentially to the formation of threo-1,2λ5-oxaphosphetanes. Oxaphosphetanes were isolated as individual compounds and their structures were confirmed by 1, 13C, and 31 NMR spectra. The fluoro-1,2λ5-oxaphosphetanes may be easily converted to various alkenylphosphonates: allyl- or vinylphosphonates. This reaction represents a good method for the preparation of phosphorylated alkenes.
