55779-10-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55779-10-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,7,7 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 55779-10:
(7*5)+(6*5)+(5*7)+(4*7)+(3*9)+(2*1)+(1*0)=157
157 % 10 = 7
So 55779-10-7 is a valid CAS Registry Number.

Cephalosporin C acylase in the autolysis of filamentous fungi

Reyes,Martinez,Alfonso,Copa-Patino,Soliveri

, p. 128 - 131 (2007/10/02)

Cephalosporin C acylase activity was studied using fluorescamine determination of free - NH2 groups produced in the deacylation of cephalosporin C by the enzyme. Fourteen fungi from different genera were studied and low extracellular cephalosporin C acylase activity was found in the genera Aspergillus, Fusarium and Penicillium. Forty one fungi of these genera were checked but not all presented acylase activity. The enzyme was generally found to be an extracellular enzyme and during the process of autolysis its activity increased with incubation time and with increasing pH of the medium. In no case was β-lactamase activity detected. Penicillium rugulosum and Penicillium griseofulvum were identified as good cephalosporin C acylase producers. Deacetyl esterase activity was also detected in these fungi.
