The CAS Registry Mumber 122928-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,9,2 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 122928-74:
(8*1)+(7*2)+(6*2)+(5*9)+(4*2)+(3*8)+(2*7)+(1*4)=129
129 % 10 = 9
So 122928-74-9 is a valid CAS Registry Number.

RECYCLIZATION REACTIONS. 26. RECYCLIZATION OF HETEROARENIUM SALTS BY ACTION OF ACID ANHYDRIDE IN THE PRESENCE OF BASE

Lipnitskii, V. F.,Shvaika, O. P.

, p. 1398 - 1403 (2007/10/02)

When oxazolium, 1,3,4-thia- and -selenodiazolium, or pyrylium salts react with acid anhydride in the presence of base, they are recyclized to pyrrole, pyrazole, and benzene derivatives, respectively.The typical features of recyclization involving anhydride in a number of five-membered systems are discussed.
