Check Digit Verification of cas no

The CAS Registry Mumber 55293-96-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,9 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55293-96:
(7*5)+(6*5)+(5*2)+(4*9)+(3*3)+(2*9)+(1*6)=144
144 % 10 = 4
So 55293-96-4 is a valid CAS Registry Number.

Synthesis of filibuvir. Part III. Development of a process for the reductive coupling of an aldehyde and a β-keto-lactone

Ide, Nathan D.,Ragan, John. A.,Bellavance, Gabriel,Brenek, Steve J.,Cordi, Eric M.,Jensen, Grace O.,Jones, Kris N.,France, Danny La,Leeman, Kyle R.,Letendre, Leo J.,Place, David,Stanchina, Corey L.,Sluggett, Gregory W.,Strohmeyer, Holly,Blunt, Jon,Meldrum, Kevin,Taylor, Stuart,Byrne, Ciaran,Lynch, Denis,Mullane, Sandra,O'Sullivan, Maria M.,Whelan, Marcella

, p. 45 - 56 (2014/05/20)

Development of a reductive coupling of a β-keto-lactone and an aldehyde is described, in which the Hantzsch ester serves as an inexpensive and convenient reducing agent. Structural features in the β-keto-lactone rendered standard reductive coupling conditions ineffective, requiring development of a specific addition and temperature protocol. Identification of one of the reactants as Ames positive required a single-digit parts per million control strategy for this impurity in the final active pharmaceutical ingredient (API).
