909797-24-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909797-24-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,7,9 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 909797-24:
(8*9)+(7*0)+(6*9)+(5*7)+(4*9)+(3*7)+(2*2)+(1*4)=226
226 % 10 = 6
So 909797-24-6 is a valid CAS Registry Number.

Synthesis of sultams by intramolecular Heck reaction
Merten, Sandra,Froehlich, Roland,Kataeva, Olga,Metz, Peter
, p. 754 - 758 (2007/10/03)
A novel access to α-methylene-γ-sultams via the intramolecular Heck reaction of α-bromovinylsulfonamides derived from allylic amines is reported. These heterocycles are potent Michael acceptors towards sulfur nucleophiles.
