Check Digit Verification of cas no

The CAS Registry Mumber 91306-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,0 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91306-23:
(7*9)+(6*1)+(5*3)+(4*0)+(3*6)+(2*2)+(1*3)=109
109 % 10 = 9
So 91306-23-9 is a valid CAS Registry Number.

Base-promoted Reactions of β-Enaminones with 2-Bromo-2-methylpropanamides. Formation of 2-Ketonyloxazolidin-4-ones and Cyclohexanespiro-oxazolidin-4-ones

Veronese, Augusto C.,Scrimin, Paolo,Vecchiati, Giorgio,Sferra, Stella,D'Angeli, Ferruccio

, p. 781 - 784 (2007/10/02)

Representative β-enaminones (1) and (2) react with N-alkyl-2-bromo-2-methylpropanamides (4a), (4b), and (4c) in the presence of NaH, to afford oxazolidin-4-ones (5) and (6) or spiro-oxazolidinone derivatives (7) and (8).The formation of an imidazolidin-4-one derivative (9) from 2-bromo-2-methylpropanilide (4c) is ascribed to the presence of an intermediate α-lactam (15).The behaviour of a spiro-oxazolidinone derivative on hydrolysis, reduction, and thiation is described.
