Check Digit Verification of cas no

The CAS Registry Mumber 1044501-34-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,4,5,0 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1044501-34:
(9*1)+(8*0)+(7*4)+(6*4)+(5*5)+(4*0)+(3*1)+(2*3)+(1*4)=99
99 % 10 = 9
So 1044501-34-9 is a valid CAS Registry Number.

Synthesis of substituted N-benzyl pyridones via an O- To N-alkyl migration

Lanni, Erica L.,Bosscher, Michael A.,Ooms, Bartel D.,Shandro, Christina A.,Ellsworth, Bruce A.,Anderson, Carolyn E.

, p. 6425 - 6428 (2008)

(Chemical Equation Presented) A new LiI-promoted O- to N-alkyl migration has been developed for the conversion of O-alkylated 2-hydroxy pyridines, quinolines, and pyrimidines to the corresponding N-alkylated heterocycles in good to excellent yields (57-99%). This method serves as an efficient means for the preparation of N-benzyl pyridones, quinolones, and pyrimidones.
