18498-65-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18498-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,9 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18498-65:
(7*1)+(6*8)+(5*4)+(4*9)+(3*8)+(2*6)+(1*5)=152
152 % 10 = 2
So 18498-65-2 is a valid CAS Registry Number.

Synthesis and Reactions of 4-Acetoxy-1-oxyazetidin-2-ones
Sheppard, Andrew,Miller, Marvin J.
, p. 2519 - 2525 (2007/10/02)
A general synthesis of 4-acetoxy-1-oxyazetidin-2-ones is described.Reaction of these compounds with certain nucleophiles caused β-lactam cleavage rather than displacement of the acetoxy group, as occurs with the simpler compound 4-acetoxyazetidin-2-one.
