Check Digit Verification of cas no

The CAS Registry Mumber 101067-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,0,6 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 101067-50:
(8*1)+(7*0)+(6*1)+(5*0)+(4*6)+(3*7)+(2*5)+(1*0)=69
69 % 10 = 9
So 101067-50-9 is a valid CAS Registry Number.

Synthesis of β-lactams from acetic acids and imines induced by phenyl dichlorophosphate reagent

Arrieta,Cossio,Palomo

, p. 1703 - 1712 (2007/10/02)

The development of a practical method for the preparation of vinylamino-β-lactams from Dane salts and Schiff bases is described. Among the reagents known to produce β-lactams from imines and acetic acids, only phenyl dichlorophosphate and 1-methyl-2-chloropyridinium iodide are suitable for the synthesis of vinylamino-β-lactams. Reaction of acetic acids with ethanolimine derivatives promoted by phenyl dichlorophosphate affords oxazolidines instead of β-lactams. Protection of the hydroxyl group as the trimethylsilyl ether in the starting Schiff bases provides a convenient route to the corresponding β-lactams instead of oxazolidines. Some observations on the scope of the method are made.
