95967-48-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 95967-48-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,9,6 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 95967-48:
(7*9)+(6*5)+(5*9)+(4*6)+(3*7)+(2*4)+(1*8)=199
199 % 10 = 9
So 95967-48-9 is a valid CAS Registry Number.

A CONVERGENT SCHEME FOR THE STEREOSELECTIVE SYNTHESIS OF 3'-NOR-1-OXACEPHEMS

Haebich, D.,Hartwig, W.

, p. 3667 - 3676 (1984)

A convergent approach to the construction of the 3-hydroxy-oxacephems 1, valuable intermediates for the synthesis of 3'-nor-1-oxacephems, is presented.The key step utilizes the Lewis acid catalyzed stereoselective ring-opening of the oxazoline 2 by an app
