Used in Cancer Prevention:
Biochem/physiol Actions
One of the primary isomers of carotene, racemic form of metabolite in carotenoid biosynthesis, biosynthesis of plant secondary metabolites, biosynthesis of terpenoids and steroids and the biosynthesis of secondary metabolites
Check Digit Verification of cas no
The CAS Registry Mumber 432-70-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 432-70:
(5*4)+(4*3)+(3*2)+(2*7)+(1*0)=52
52 % 10 = 2
So 432-70-2 is a valid CAS Registry Number.

Kinetic Model for Studying the Isomerization of α- and β-Carotene during Heating and Illumination
Chen, B. H.,Chen, T. M.,Chien, J. T.
, p. 2391 - 2397 (2007/10/02)
The thermoisomerization and iodine-catalyzed photoisomerization of all-trans-α- and all-trans-β-carotene were kinetically studied using regression models. Carotene samples were heated at varied temperatures or exposed to a 20 W light for varied lengths of time. Isomerization and degradation reactions were monitored using HPLC with diode array detection. Four cis isomers of β-carotene and three cis isomers of α-carotene were separated and detected. The degradations of both carotenes under heating at 150 deg C or iodine/light treatment may fit the reversible first- order model. 9-cis and 13-cis were the major β-carotene isomers formed during heating, while 13,15-di-cis was favored during iodine-catalyzed photoisomerization. The formation of 9-cis and 13-cis form all-trans-α-carotene was dependent upon the extent of heat or iodine/light treatment, and the latter was formed in greater amount under either treatment.
