66495-46-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66495-46-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,9 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66495-46:
(7*6)+(6*6)+(5*4)+(4*9)+(3*5)+(2*4)+(1*6)=163
163 % 10 = 3
So 66495-46-3 is a valid CAS Registry Number.

A NATURAL PRODUCT WAS SHOWN TO BE OF LOW OPTICAL PURITY: SYNTHESIS OF (2S,5R,6E,8E)-2,5-EPOXY-6,8-MEGASTIGMADIENE, ITS (6Z,8E)-ISOMER AND (2S,6R,7S,8E)-2,7-EPOXY-4,8-MEGASTIGMADIENE, THE CONSTITUENTS OF OSMANTHUS ABSOLUTE

Mori, Kenji,Tamura, Hiroshi

, p. 2643 - 2646 (2007/10/02)

The title compounds were synthesized from (S)-3-hydroxy-2,2-dimethylcyclohexanone. (6E,8E)-2,5-Epoxy-6,8-megastigmadiene isolated as a minor constituent of Osmanthus absolute was shown to be of only ca. 11percent e.e. enriched in (2S,5R)-(+)-isomer.
