Check Digit Verification of cas no

The CAS Registry Mumber 97222-14-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,2 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 97222-14:
(7*9)+(6*7)+(5*2)+(4*2)+(3*2)+(2*1)+(1*4)=135
135 % 10 = 5
So 97222-14-5 is a valid CAS Registry Number.

Synthesis of a Cyclobutanone Analogue of a β-Lactam Antibiotic

Lowe, Gordon,Swain, Steven

, p. 391 - 398 (2007/10/02)

A route has been developed which allows cyclobutanone analogues of β-lactam antibiotics to be synthesized and is illustrated by the synthesis of 6-oxo-7β-phenylacetamido-2-oxabicycloheptane-4α-carboxylic acid.Although this analogue (which contained some 7α-epimer) did not show significant antibacterial activity it was a weak inhibitor of Streptomyces R61 D,D-carboxypeptidase and a time-dependent inhibitor of E.coli R-TEM and B. cereus type I β-lactamases. 7β-Chloro-6-oxo-2-oxabicycloheptane-4α-carboxylic acid also exhibited time-dependent inhibition of these β-lactamases.
