89229-78-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89229-78-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,2 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89229-78:
(7*8)+(6*9)+(5*2)+(4*2)+(3*9)+(2*7)+(1*8)=177
177 % 10 = 7
So 89229-78-7 is a valid CAS Registry Number.

N-ALKYLATION OF ENAMINONES
Greenhill, John V.,Moten, Ashraf M.
, p. 3405 - 3408 (2007/10/02)
The base catalyzed N-alkylation of a series of primary and secondary enaminones has been examined in detail.The enaminone anion was found to be a weak nucleophile.Best results were obtained in tetrahydrofuran or dioxane with sodium hydride and an alkyl io
