Check Digit Verification of cas no

The CAS Registry Mumber 71919-14-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,1 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 71919-14:
(7*7)+(6*1)+(5*9)+(4*1)+(3*9)+(2*1)+(1*4)=137
137 % 10 = 7
So 71919-14-7 is a valid CAS Registry Number.

Phenytoin prodrugs III: Water-soluble prodrugs for oral and/or parenteral use

Varia,Schuller,Sloan,Stella

, p. 1068 - 1073 (1984)

Various bioreversible derivatives of phenytoin, a poorly water soluble and erratically absorbed drug after both oral and parenteral dosing, were synthesized. Initial evaluation of these expected prodrugs, i.e., their aqueous solubility, cleavage in the presence of various animal tissues, and anticonvulsant activity in mice, confirmed that a number of the derivatives did indeed behave as prodrugs. The more promising prodrugs were the disodium phosphate ester and various amino groups containing acyl esters of 3-(hydroxymethyl)-5,5-diphenylhydantoin.
