Check Digit Verification of cas no

The CAS Registry Mumber 1228657-90-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,6,5 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1228657-90:
(9*1)+(8*2)+(7*2)+(6*8)+(5*6)+(4*5)+(3*7)+(2*9)+(1*0)=176
176 % 10 = 6
So 1228657-90-6 is a valid CAS Registry Number.

Synthesis, structure and conformational analysis of 2,4-diaryl-3-azabicyclo[3.3.1]nonan-9-one thiosemicarbazones and semicarbazones

Ramachandran,Rani,Kabilan

experimental part, p. 42 - 50 (2010/09/06)

A series of thiosemicarbazones and semicarbazones have been synthesized and characterized by one and two dimensional NMR spectroscopy. The possible ring conformations of both the hydrazones are discussed. The chemical shifts and coupling constants suggest that the reported hydrazones adopt twin-chair conformations with equatorial orientation of the aryl substituents. Besides, the proposed conformations are further confirmed by single crystal X-ray diffraction analysis and molecular optimization geometry method. Crown Copyright
