64617-99-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64617-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,1 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 64617-99:
(7*6)+(6*4)+(5*6)+(4*1)+(3*7)+(2*9)+(1*9)=148
148 % 10 = 8
So 64617-99-8 is a valid CAS Registry Number.

Dinuclear μ-alkylidene complexes of transition metals as models for the transformation of CH2X2 (X=Cl, Br, I) into malonic acid derivatives by double carbonylation reactions

Denise, B.,Navarre, D.,Rudler, H.,Daran, J. C.

, p. 273 - 289 (2007/10/02)

The carbonylation of the μ-alkylidene complexes Fe2(CO)8CH2 (1) and Pd2I2(PPh2CH2PPh2)2CH2 (2) has been studied under a variety of conditions.In the presence of an alcohol ROH, complex 1 gives mainly the acetate CH3CO2R, the product of monocarbonylation, whereas under the same conditions complex 2 gives the malonate CH2(CO2R)2, the product of dicarbonylation.The mechanisms of both reactions are discussed.From the fraction involving 1 a mononuclear complex resulting from the dimerization of ketene has been isolated, and its structure established by an X-ray diffraction study.Olefins such as ethene and norbornene are able to trap the ketene intermediate.The possible participation of such μ-alkylidene complexes in the direct transformation of CH2X2 (X=Cl, Br, I) into malonic acid derivatives is discussed.
