Check Digit Verification of cas no

The CAS Registry Mumber 85995-67-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,9 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 85995-67:
(7*8)+(6*5)+(5*9)+(4*9)+(3*5)+(2*6)+(1*7)=201
201 % 10 = 1
So 85995-67-1 is a valid CAS Registry Number.

Geminal acylation of α-heterosubstituted cyclohexanones and their ketals

Pottie, Ian R.,Crane, Sheldon N.,Gosse, Anna Lee,Miller, David O.,Burnell, D. Burnell

, p. 1118 - 1124 (2011/01/09)

Geminal acylation of derivatives of cyclohexanone with Br, Cl, F, and OCH3 in the α position, and of their corresponding dimethyl ketals, could not be accomplished to a significant extent following published procedures. The transformation was a

Intermolecular cross-double-Michael addition between nitro and carbonyl activated olefins as a new approach in C-C bond formation

Sun, Xiaohua,Sengupta, Sujata,Petersen,Wang, Hong,Lewis, James P.,Shi, Xiaodong

, p. 4495 - 4498 (2008/03/14)

(Chemical Equation Presented) A novel intermolecular cross-double-Michael addition between nitro and carbonyl activated olefins has been developed through Lewis base catalysis. The reaction took place with a large group of β-alkyl nitroalkenes and α,β-uns

Novel Acylation of Aliphatic Olefins Promoted by Active Zinc Compounds

Shono, Tatsuya,Nishiguchi, Ikuzo,Sasaki, Manji,Ikeda, Haruhiko,Kurita, Makoto

, p. 2503 - 2505 (2007/10/02)

It was found that acylation of a variety of aliphatic olefins with acid chlorides is efficiently promoted by active zinc compounds, which were prepared from a Zn/Cu couple and alkyl iodides.The crude product mixtures were subsequently treated with 1 M KOH in methanol or were subjected to catalytic hydrogenation to afford the corresponding α,β-unsaturated or saturated ketones in good to moderate yields.It was also shown that the reaction fully follows the Markovnikov rule.
