Check Digit Verification of cas no
The CAS Registry Mumber 253349-41-6 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, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 253349-41:
(8*2)+(7*5)+(6*3)+(5*3)+(4*4)+(3*9)+(2*4)+(1*1)=136
136 % 10 = 6
So 253349-41-6 is a valid CAS Registry Number.

Benzosilacyclohexadienones: Synthesis and reactivity
Kende, Andrew S.,Mineur, Catherine M.,Lachicotte, Rene J.
, p. 7901 - 7906 (1999)
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.
