143308-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143308-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,0 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143308-06:
(8*1)+(7*4)+(6*3)+(5*3)+(4*0)+(3*8)+(2*0)+(1*6)=99
99 % 10 = 9
So 143308-06-9 is a valid CAS Registry Number.

Reactions and Rearrangements in 2-Oxabicycloheptanones
Naidorf-Meir, Simha,Hassner, Alfred
, p. 5102 - 5105 (2007/10/02)
The furan-fused chlorocyclobutanone 6 undergoes reaction with O, N, S, C nucleophiles at a much slower rate than its pyran homolog, wich is attributed to a reluctance to enolization.Instead of substitution products, rearranged products were formed.For ins
