Check Digit Verification of cas no

The CAS Registry Mumber 104263-95-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,6 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104263-95:
(8*1)+(7*0)+(6*4)+(5*2)+(4*6)+(3*3)+(2*9)+(1*5)=98
98 % 10 = 8
So 104263-95-8 is a valid CAS Registry Number.

Time-dependent inhibitors of the enzyme human leukocyte elastase have been developed based on the cephem nucleus. A series of cephalosporin tert-butyl esters has been examined, and the activity of these compounds has been found to be very sensitive to C-7
