The CAS Registry Mumber 97799-96-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,7,9 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97799-96:
(7*9)+(6*7)+(5*7)+(4*9)+(3*9)+(2*9)+(1*6)=227
227 % 10 = 7
So 97799-96-7 is a valid CAS Registry Number.

BECKMANN REARRANGEMENT OF ACETYLTHIOPHENE OXIME BENZENESULFONATES AS A METHOD FOR THE SYNTHESIS OF ACETAMIDOTHIOPHENES

Fabrichnyi, B. P.,Bulgakova, V. N.,Gol'dfarb, Ya. L.

, p. 401 - 403 (1985)

The Beckmann rearrangement of 2-acetylthiophene, 5-methyl-2-acetylthiophene, 5-chloro-2-acetylthiophene, and 2,5-dichloro-3-acetylthiphene oxime benzenesulfonates to the corresponding acetamidothiophenes was carried out by heating with an aqueous methanol solution of sodium acetate.This method can be used for the preparative synthesis of 2-acetamidothiophene and 2,5-dichloro-3-acetamidothiophene.
