128040-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128040-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,4 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128040-90:
(8*1)+(7*2)+(6*8)+(5*0)+(4*4)+(3*0)+(2*9)+(1*0)=104
104 % 10 = 4
So 128040-90-4 is a valid CAS Registry Number.

Effects of iodide ion and amines on the free radical alkylation of 1,4-enediones by alkylmercury halides
Russell,Kim
, p. 6273 - 6276 (1990)
Iodide ion promotes the photostimulated reductive alkylation of α,β-unsaturated ketones by electron transfer from RHgI2- to the adduct enolyl radicals. Amines such as Dabco can promote oxidative alkylation by removal of a proton from the adduct
