86951-25-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 86951-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,9,5 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 86951-25:
(7*8)+(6*6)+(5*9)+(4*5)+(3*1)+(2*2)+(1*5)=169
169 % 10 = 9
So 86951-25-9 is a valid CAS Registry Number.

Synthesis of Benzocarbacephem and Benzocarbapenem Derivatives by Copper-promoted Intramolecular Aromatic Substitution

Joyeau, Roger,Yadav, Lal D. S.,Wakselman, Michel

, p. 1899 - 1908 (2007/10/02)

Copper-mediated cyclisation of 4-azetidinones and 4-azetidinones proved to be a route to benzocarbacephem and benzocarbapenem derivatives respectively.The effect of functionalities present in the alkyl part of the ring to be formed was considered with regard to cyclisation efficiency and further chemical modifications.Conversion, into halide, of the diastereoisomeric mixture (4R,6S; 4S,6R; 4R,6R; and 4S,6S) of t-butyl 2-hydroxybenzocarbacephem-4'-carboxylate (14f) afforded either the chloride (17a) as racemic diastereoisomers or the fluoride (17c) as a single racemic diastereoisomer.The corresponding free carboxylic acids (18a, c) were designed as inactivators of beta-lactamases.
