Check Digit Verification of cas no
The CAS Registry Mumber 5227-71-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,2 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5227-71:
(6*5)+(5*2)+(4*2)+(3*7)+(2*7)+(1*1)=84
84 % 10 = 4
So 5227-71-4 is a valid CAS Registry Number.

Some spiro I and spiro II substituted by different groups were synthesized in order to evaluate their photochromic properties and to optimize the preparation of spiroheterocyclic systems.In addition, some spiro III were also prepared as reference compounds.Their physical and spectroscopic characteristics (UV, 1H and 13C) were determined.A study using the experimental design methodology allowed to point out the most important factors for improving the reaction yields. KEYWORDS: Photochromism, spirooxazines, spiropyrans, synthesis, 1H NMR, experimental design methodology.
