284022-85-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 284022-85-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,4,0,2 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 284022-85:
(8*2)+(7*8)+(6*4)+(5*0)+(4*2)+(3*2)+(2*8)+(1*5)=131
131 % 10 = 1
So 284022-85-1 is a valid CAS Registry Number.

Copper catalyzed conjugate addition of highly functionalized arylmagnesium compounds to enones
Varchi, Greta,Ricci, Alfredo,Cahiez, Gérard,Knochel, Paul
, p. 2727 - 2731 (2000)
Highly functionalized arylmagnesium bromides are readily prepared by an iodine-magnesium exchange reaction. In the presence of catalytic amounts of copper(I) salts and chlorotrimethylsilane, they add to various enones leading to the conjugate addition pro
