Check Digit Verification of cas no

The CAS Registry Mumber 112252-21-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,2,5 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112252-21:
(8*1)+(7*1)+(6*2)+(5*2)+(4*5)+(3*2)+(2*2)+(1*1)=68
68 % 10 = 8
So 112252-21-8 is a valid CAS Registry Number.

DIELS-ALDER REACTIONS OF 4,4-DIMETHYL-2-CYCLOHEXENONES. A DIRECT ROUTE TO THE 4,4-DIMETHYL-1-DECALONES

Liu, Hsing-Jang,Browne, Eric N. C.

, p. 1262 - 1278 (2007/10/02)

Diels-Alder additions to enones 1 and 2, synthetic equivalents of the synthon 3, were studied using a variety of hydrocarbon dienes.The two enones have been shown to be effective and synthetically useful dienophiles.Spectroscopic (especially 1H and 13C magnetic resonance) and chemical techniques were used to define unambiguously the full structures of the adducts.The structures of the various reaction products were used to draw qualitative conclusions about the nature of the transition states involved and the various electronic and steric effects that play a role in the mechanistic course of the Diels-Alder reaction.
