Check Digit Verification of cas no

The CAS Registry Mumber 20005-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,0 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20005-32:
(7*2)+(6*0)+(5*0)+(4*0)+(3*5)+(2*3)+(1*2)=37
37 % 10 = 7
So 20005-32-7 is a valid CAS Registry Number.

Obtention d'aldehydes γ-fonctionnels au cours de la thermolyse du percarbonate de O,O-t-butyle et O-vinyle en solution

Filliatre, Claude,Villenave, Jean-Jacques,Jaouhari, Rabih,Baratchart, Michel

, p. 352 - 356 (2007/10/02)

Owing to its peroxyester group, O,O-tert-butyl and O-vinyle peroxycarbonate may act as a free radical initiator in solution, but also, due to the presence of the vinylic insaturation, as a substrate for free radical addition reactions. - In such solvents as cumene which give free radicals unable to add to the double bond, the peroxycarbonate merely behaves as a vinyloxy radicals generator.It is thus possible to observe these radicals reacting either as formylmethyl radicals or as acetyl radicals. - In solvents such as cyclohexane which give free radicals able to add to the double bond, the reaction results in the substitution of formylmethyl groups to labile hydrogens of the solvent. - By applying the reaction to such compounds as ketones, ethers, acids and their derivatives, we could obtain γ-functional aldehydes (γ-ketoaldehydes, γ-oxaaldehydes and derivatives of succinaldehydic acids).These products are often difficult to prepare by other routes and until now only some of them have been described.
