70302-37-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70302-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,0 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70302-37:
(7*7)+(6*0)+(5*3)+(4*0)+(3*2)+(2*3)+(1*7)=83
83 % 10 = 3
So 70302-37-3 is a valid CAS Registry Number.

Use of 1,3-Dioxin-4-ones and Their Related Compounds in Synthesis. Part 28 . Asymmetric de Mayo Reactions Using Chiral Spirocyclic Dioxinones

Sato, Masayuki,Abe, Yoshito,Takayama, Kazuhisa,Sekiguchi, Keiko,Kaneko, Chikara,et al.

, p. 241 - 252 (2007/10/02)

The use of rigid spirocyclic dioxinones having 1-menthone as the chiral auxiliary as the enones in the photocycloaddition reactions opened novel methods for obtaining enantiomerically pure compounds, such as iridoids.Convex side preference of the sofa-conformation of these dioxinones in the photoaddition to cyclopentene increases up to 100percent by introducing either a bulky substituent or 5-hexenyl group at the 3-position to these dioxinones and, hence, highly asymmetric inter- and intramolecular de Mayo reactions have been disclosed.
