85901-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85901-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,0 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85901-33:
(7*8)+(6*5)+(5*9)+(4*0)+(3*1)+(2*3)+(1*3)=143
143 % 10 = 3
So 85901-33-3 is a valid CAS Registry Number.

Low-melting phenytoin prodrugs as alternative oral delivery modes for phenytoin: A model for other high-melting sparingly water-soluble drugs
Yamaoka,Roberts,Stella
, p. 400 - 405 (2007/10/02)
Phenytoin is a high-melting, weakly acidic, and sparingly water-soluble drug. Because of these physicochemical properties, phenytoin is subject to erratic bioavailability in a variety of dosage forms both in its acidic as well as sodium salt forms. A homo
