698351-70-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 698351-70-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,8,3,5 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 698351-70:
(8*6)+(7*9)+(6*8)+(5*3)+(4*5)+(3*1)+(2*7)+(1*0)=211
211 % 10 = 1
So 698351-70-1 is a valid CAS Registry Number.

Generic synthesis of β-sultams via domino alkylation of bromomethanesulfonamides
Barton, William R.S.,Paquette, Leo A.
, p. 113 - 119 (2007/10/03)
Reaction of N-substituted bromomethanesulfonamides with 2 equiv of potassium carbonate and an α-halo ketone, ester, or nitrile leads directly to 3-substituted β-sultams. The first step is intermolecular and is followed by an intramolecular alkylation. The
