1147856-08-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1147856-08-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,7,8,5 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1147856-08:
(9*1)+(8*1)+(7*4)+(6*7)+(5*8)+(4*5)+(3*6)+(2*0)+(1*8)=173
173 % 10 = 3
So 1147856-08-3 is a valid CAS Registry Number.

Sc(OTf)3-catalyzed conjugate allylation of alkylidene meldrum's acids
Dumas, Aaron M.,Fillion, Eric
supporting information; experimental part, p. 1919 - 1922 (2009/09/25)
Alkylidene Meldrum's acids are allylated in a conjugate fashion by allyltin nucleophiles under mild Sc(OTf)3-catalyzed conditions. The addition is functional group tolerant and reactions with nonracemic alkylidenes are highly diastereoselective
