Check Digit Verification of cas no
The CAS Registry Mumber 137846-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,4 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137846-89:
(8*1)+(7*3)+(6*7)+(5*8)+(4*4)+(3*6)+(2*8)+(1*9)=170
170 % 10 = 0
So 137846-89-0 is a valid CAS Registry Number.

Absolute Stereochemistry of Exogonic Acid
Lawson, Elvie N.,Jamie, Joanne F.,Kitching, William
, p. 353 - 358 (1992)
Exogonic acid (2-(carboxymethyl)-7-methyl-1,6-dioxaspirononane), a resin constituent of the Brazilian tree Ipomoea operculata (Martin) is demonstrated to be predominantly the E,E and Z,Z diastereomers, with the 2S,5S,7R and 2S,5R,7R configurations, respectively.Minor amounts of the 2R,5S,7R E,Z and 2R,5R,7R Z,E isomers are also present.These conclusions are based on chiral gas chromatographic analyses of suitable derivatives and enantioselective syntheses employing (S)-1,2-epoxypropane and (2S)-4-oxy>-1,2-epoxybutane as alkylating agents for anions of acetone N,N-dimethylhydrazone.
