Check Digit Verification of cas no

The CAS Registry Mumber 1099629-83-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,9,6,2 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1099629-83:
(9*1)+(8*0)+(7*9)+(6*9)+(5*6)+(4*2)+(3*9)+(2*8)+(1*3)=210
210 % 10 = 0
So 1099629-83-0 is a valid CAS Registry Number.

Sc(OTf)3-catalyzed dehydrogenative cyclization for synthesis of N-methylacridones

Li, Xi-An,Wang, Hong-Li,Yang, Shang-Dong

, p. 1794 - 1797 (2013/05/23)

A novel method has been developed for the synthesis of substituted N-methylacridones from 2-(N-methyl-N-phenylamino)benzaldehydes via dehydrogenative cyclization. This transformation involves two primary processes: the aldehyde first coordinates with Sc(OTf)3 and induces the aromatic electrophilic substitution (SEAr) reaction to form the active intermediate N-methyl-acridin-9-ol, which is then quickly oxidized in situ to afford the acridones. Furthermore, the procedure involved is both environmental friendly and atom efficient; H2O is the only byproduct in this reaction.
