Check Digit Verification of cas no

The CAS Registry Mumber 43128-39-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,1,2 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 43128-39:
(7*4)+(6*3)+(5*1)+(4*2)+(3*8)+(2*3)+(1*9)=98
98 % 10 = 8
So 43128-39-8 is a valid CAS Registry Number.

Convenient methods for retro-aldol reactions of a, β-unsaturated ketones in micellar media under acidic or basic conditions are proposed that enable obtaining optically pure (3R)-methylcyclohexanone and (1R,4R)-4- methylmenthone in high yields. Springer-V

Synthesis and Chiroptical Properties of Some Piperidin-2-ones

Jackman, L. M.,Webb, R. Lee,Yick, H. C.

, p. 1824 - 1831 (2007/10/02)

The synthesis of optically pure (R)-(+)-4-isopropylpiperidin-2-one, (R)-(+)-4-isopropyl-4-methylpiperidin-2-one, and (R)-(+)-5-methylpiperidin-2-one in high yields from monocyclic terpene precursors are described.The CD spectra of these compounds are reported, and the chiroptical properties of δ-lactams are examined in terms of current theories for the amide chromophore.It is concluded that slight, conformationally induced nonplanarity of the amide chromophore is responsible for signs of the longest wavelenght bands in the CD spectra of these and related compounds.
