653-89-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 653-89-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 653-89:
(5*6)+(4*5)+(3*3)+(2*8)+(1*9)=84
84 % 10 = 4
So 653-89-4 is a valid CAS Registry Number.

Further studies on the catalysis of hydrolysis and aminolysis of benzylpenicillin by metal chelates

Tomida,Schwartz

, p. 331 - 335 (1983)

It was suggested previously that the very rapid catalysis of benzylpenicillin hydrolysis and aminolysis by zinc ion and tris(hydroxymethyl)aminomethane (tromethamine) was mediated by a ternary complex in which the metal ion not only held the substrate and
