Check Digit Verification of cas no

The CAS Registry Mumber 623564-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,5,6 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 623564-98:
(8*6)+(7*2)+(6*3)+(5*5)+(4*6)+(3*4)+(2*9)+(1*8)=167
167 % 10 = 7
So 623564-98-7 is a valid CAS Registry Number.

-

Page/Page column 29, (2010/11/25)

This invention relates to certain bicyclic 6-alkylidene penems which act as a inhibitor of class-D enzymes. β-Lactamases hydrolyze β-lactam antibiotics, and as such serve as the primary cause of bacterial resistance. The compounds of the present invention when combined with β-lactam antibiotics will provide an effective treatment against life threatening bacterial infections. In accordance with the present invention there are provided compounds of general formula I or a pharmaceutically acceptable salt or in vivo hydrolyzable ester R5 thereof: wherein: One of A and B denotes hydrogen and the other an optionally substituted fused bicyclic heteroaryl group; and X═O or S.
