269742-76-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 269742-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,9,7,4 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 269742-76:
(8*2)+(7*6)+(6*9)+(5*7)+(4*4)+(3*2)+(2*7)+(1*6)=189
189 % 10 = 9
So 269742-76-9 is a valid CAS Registry Number.

A total synthesis of (1R,5R)-3-phenylmethyl-4-thia-2,6-diazabicyclo [3.2.0]hept-2-en-7-one, a useful intermediate for the preparation of penem and cepham derivatives

Cainelli, Gianfranco,Giacomini, Daria,Galletti, Paola

, p. 289 - 294 (2007/10/03)

The preparation of the thiazoline (1R,5R)-3-phenylmethyl-4-thia-2,6- diazabicyclo [3.2.0]hept-2-en-7-one (1) is presented. This compound, which has been extensively used as an intermediate for the synthesis of penems and cephams, has been obtained starting from a C-4 unsubstituted azetidinone by means of facile processes while chirality has been obtained through enzymatic resolution.
