141266-75-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141266-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,6 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 141266-75:
(8*1)+(7*4)+(6*1)+(5*2)+(4*6)+(3*6)+(2*7)+(1*5)=113
113 % 10 = 3
So 141266-75-3 is a valid CAS Registry Number.

Synthesis and rearrangement of dispiro-epoxy-β-lactams
Williams
, p. 1017 - 1021 (2007/10/02)
α-Methylene-β-lactams are prepared by a Peterson olefination reaction. These substrates can be epoxidized with MCPBA to give the title dispiro-epoxy-β-lactams. Under the influence of boron trifluoride, these substrates rearrange to spiro-3-ketolactams.
