Check Digit Verification of cas no

The CAS Registry Mumber 503003-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,0,0 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 503003-76:
(8*5)+(7*0)+(6*3)+(5*0)+(4*0)+(3*3)+(2*7)+(1*6)=87
87 % 10 = 7
So 503003-76-7 is a valid CAS Registry Number.

Thallium trinitrate mediated oxidation of 3-alkenols: Ring contraction vs cyclization

Ferraz, Helena M. C.,Longo Jr., Luiz S.,Zukerman-Schpector, Julio

, p. 3518 - 3521 (2007/10/03)

The reaction of a series of six-membered ring 3-alkenols with thallium trinitrate (TTN) in three different experimental conditions was studied. Either cyclization products or ring contraction products were obtained, depending on the structure of the substrate as well as the nature of the solvent. The reaction of a seven-membered ring 3-alkenol with TTN led to the ring contraction product exclusively.
