51655-65-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51655-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,6,5 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 51655-65:
(7*5)+(6*1)+(5*6)+(4*5)+(3*5)+(2*6)+(1*5)=123
123 % 10 = 3
So 51655-65-3 is a valid CAS Registry Number.

From vinyl sulfides, sulfoxides and sulfones to vinyl zirconocene derivatives

Farhat, Shahera,Zouev, Irena,Marek, Ilan

, p. 1329 - 1337 (2007/10/03)

An easy and straightforward new method for the preparation of sp 2 zirconocene derivatives from a wide range of heterosubstituted alkenes such as vinyl sulfides, sulfoxides and sulfones is described. In all cases, a complete isomerization of the stereochemistry is observed and only the E-isomer is obtained. The reactivity of the resulting vinylic organometallic can be increased by a transmetalation reaction into organocopper, organozinc or organopalladium species and, therefore, several carbon-carbon formation were easily realized.

New Synthetic Methods, 7. - β-Ketosulfones, Useful Ethylenediide Equivalents for the Preparation of Olefins and the Synthesis of 6-Nonen-1-ol, the Sex Attractant of the Mediterranean Fruit Fly (Ceratitus capitata)

Scholz, Dieter

, p. 98 - 106 (2007/10/02)

β-Ketosulfones, which form dianions (α and γ position), are alkylated in both positions.Brominating cleavage gives α-bromosulfones which, by Ramberg-Baecklund rearrangement, form olefins.The synthesis of 6-nonen-1-ol, starting from 2-(methylsulfonyl)cyclohexanone, is described.
