Check Digit Verification of cas no

The CAS Registry Mumber 121429-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,2 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121429-35:
(8*1)+(7*2)+(6*1)+(5*4)+(4*2)+(3*9)+(2*3)+(1*5)=94
94 % 10 = 4
So 121429-35-4 is a valid CAS Registry Number.

TOTAL SYNTHESIS OF VARIOUS ELEMANOLIDES

Friedrich, Dirk,Bohlmann, Ferdinand

, p. 1369 - 1392 (2007/10/02)

Starting with a suitable substituted divinyl cyclohexanone, eleven naturally occurring 12.8-elemanolides bearing exo-methylene or methyl groups at C-11 and differing in substitution as well as in relative configuration, have been synthesized in racemic form.An approach to elemanolides with additional oxygen functionalities is principally possible by modification of the basic concept.Methods for the oxidative generation of terpenoid exo-methylene lactone and furan units are exemplified by synthesis of menthofuran and the p-menthenolides from isopulegols.
