Check Digit Verification of cas no

The CAS Registry Mumber 1334513-09-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,5,1 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1334513-09:
(9*1)+(8*3)+(7*3)+(6*4)+(5*5)+(4*1)+(3*3)+(2*0)+(1*9)=125
125 % 10 = 5
So 1334513-09-5 is a valid CAS Registry Number.

Mechanism-Based Solution to the ProTide Synthesis Problem: Selective Access to Sofosbuvir, Acelarin, and INX-08189

Simmons, Bryon,Liu, Zhuqing,Klapars, Artis,Bellomo, Ana,Silverman, Steven M.

supporting information, p. 2218 - 2221 (2017/05/12)

A general and efficient method for the synthesis of pronucleotide (ProTide) 5'-phosphoramidate monoesters is reported. This method consists of a highly stereoselective 5'-phosphorylation mediated by dimethylaluminum chloride to afford the desired target ProTides in excellent yields without employing 3'-protection strategies. The application of this methodology to the synthesis of a number of pharmaceutically relevant compounds currently marketed or under investigation in clinical research is demonstrated.
