191027-57-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 191027-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,0,2 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 191027-57:
(8*1)+(7*9)+(6*1)+(5*0)+(4*2)+(3*7)+(2*5)+(1*7)=123
123 % 10 = 3
So 191027-57-3 is a valid CAS Registry Number.

Novel synthesis of degradation products of carotenoids, megastigmatrienone analogues and blumenol-A

Ito, Nobuhiko,Etoh, Takeaki,Hagiwara, Hisahiro,Kato, Michiharu

, p. 1571 - 1579 (2007/10/03)

Synthesis of 4-alkylidene-3,5,5-trimethylcyclohex-2-enones 7 has been achieved utilising 1,4-conjugate dehydrobromination of allylic bromides 5 as a key step. This chemical transformation is applied to the synthesis of degradation products of carotenoids: megastigmatrienones 7e/1-4,4-methylene-3,5,5-trimethylcyclohex-2-enone 7a, 4-(3-hydroxybutylidene)-3,5,5-trimethylcyclohex-2-enone 9,1,3,7,7-tetramethyl-2-oxabicyclo[4.4.0]dec-5-en-9-one 10a-b and 3,4,7,8-tetrahydro-4,4,7-trimethylnaphthalen-2(6H)-one 15. A novel photoisomerisation of 4-[(Z)-3-acetoxybut-2-enyl]-4-hydroxy-3,5,5-trimethylcyclohex-2-enone 19 to 4-[(E)-3-acetoxybut-2-enyl]-4-hydroxy-3,5,5-trimethylcyclohex-2-enone 20 enables us to synthesise blumenol-A 21.
