253349-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 253349-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,3,4 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 253349-39:
(8*2)+(7*5)+(6*3)+(5*3)+(4*4)+(3*9)+(2*3)+(1*9)=142
142 % 10 = 2
So 253349-39-2 is a valid CAS Registry Number.

Benzosilacyclohexadienones: Synthesis and reactivity
Kende, Andrew S.,Mineur, Catherine M.,Lachicotte, Rene J.
, p. 7901 - 7906 (2007/10/03)
The synthesis and the allylic oxidation reaction of new benzosilacyclohexenes are described. The reactivity of these new cyclic β-silyl-α,β-unsaturated ketones in cycloaddition reactions, as well as in 1,4-addition reactions, is discussed.
