Check Digit Verification of cas no

The CAS Registry Mumber 157552-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,5,5 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 157552-23:
(8*1)+(7*5)+(6*7)+(5*5)+(4*5)+(3*2)+(2*2)+(1*3)=143
143 % 10 = 3
So 157552-23-3 is a valid CAS Registry Number.

Epoxy-pyronene: Obtention of cyclocitrals from ionones and precursor of new terpenic compounds

Marc,Soulet,Serramedan,Delmond

, p. 3381 - 3388 (2007/10/02)

The selective obtention of epoxy-pyronene from δ-pyronene has been realized using metachloroperbenzoic acid. The isomerization of this epoxidic compound with Lewis and protonic acids and on active alumina has been studied leading to cyclocitrals. Ionones are obtained from epoxy-pyronene by homologation with various C3 units, in the presence of paratoluenesulfonic acid in order to obtain β-cyclocitral in situ. New terpenic compounds with the cyclogeranyl skeleton were obtained from epoxy-pyronene by reduction followed by homologation.
