Check Digit Verification of cas no

The CAS Registry Mumber 191469-76-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,4,6 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 191469-76:
(8*1)+(7*9)+(6*1)+(5*4)+(4*6)+(3*9)+(2*7)+(1*6)=168
168 % 10 = 8
So 191469-76-8 is a valid CAS Registry Number.

Efficient synthesis of new asymmetric tripodal ligands using microwave irradiation, and their crystal structures

Yuan, Zeli,Yang, Xiaoqing,Wang, Lei,Huang, Jiandong,Wei, Gang

, p. 42211 - 42214 (2015/02/03)

An efficient method for the synthesis of asymmetric tripodal ligands from aryl aldehydes and (2-hydro-xybenzyl-2-pyri-dylmethyl)amine was developed. It has the advantages of short reaction times, high yields and a simple methodology. The title ligands were characterized using a combination of 1H NMR, 13C NMR, FT-IR and H RMS spectroscopies. The structures of some of the ligand were confirmed by single-crystal X-ray diffraction. This journal is
