Check Digit Verification of cas no
The CAS Registry Mumber 139396-63-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,9 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139396-63:
(8*1)+(7*3)+(6*9)+(5*3)+(4*9)+(3*6)+(2*6)+(1*3)=167
167 % 10 = 7
So 139396-63-7 is a valid CAS Registry Number.

THE SIGMATROPIC REARRANGEMENT OF SULFILIMINES FROM 3-EXOMETHYLENECEPHAMS
Snyder, Nancy J.,Paschal, Jonathan W.,Elzey, Thomas K.,Spry, Douglas O.
, p. 2193 - 2204 (2007/10/02)
3-Exomethylenecepham sulfides react with phthalimidonitrene and the resulting sulfilimine undergoes a sigmatropic rearrangement to give the 1,2,6-thiadiazepine azetidinone ring system.
