32811-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 32811-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,8,1 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 32811-25:
(7*3)+(6*2)+(5*8)+(4*1)+(3*1)+(2*2)+(1*5)=89
89 % 10 = 9
So 32811-25-9 is a valid CAS Registry Number.

Tandem chain extension-homoenolate formation: The formation of α-methylated-γ-keto esters
Hilgenkamp, Ramona,Zercher, Charles K.
, p. 3037 - 3040 (2001)
matrixpresented A tandem chain extension-homoenolate formation reaction is described. The treatment of β-keto esters with the Furukawa reagent followed by exposure to a catalytic amount of trimethylsilyl chloride provides access to an ester homoenolate.
