877077-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 877077-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,0,7 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 877077-66:
(8*8)+(7*7)+(6*7)+(5*0)+(4*7)+(3*7)+(2*6)+(1*6)=222
222 % 10 = 2
So 877077-66-2 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.
