120092-51-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 120092-51-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,0,9 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 120092-51:
(8*1)+(7*2)+(6*0)+(5*0)+(4*9)+(3*2)+(2*5)+(1*1)=75
75 % 10 = 5
So 120092-51-5 is a valid CAS Registry Number.

A facile access to optically active ring C aromatic diterpene derivatives. Highly efficient synthesis of (+)-12-methyl-7-oxopodocarpa-8,11,13-triene-13-carboxylic acid and (+)-13-methyl-7-oxopodocarpa-8,11,13-triene-12-carboxylic acid from manool

Nakano,Alonso,Maillo,Martin,Nunez

, p. 3801 - 3804 (1995)

The extension of our recently developed strategy using the diene 6 as a key intermediate to the synthesis of naturally occurring ring C aromatic diterpene derivatives provided compounds 1a and 2a in five steps from manool 5. However, the physical and spectroscopic properties of either of these synthetic materials did not agree with those reported for margolone, isolated from Azadirachta indica A. Juss. This indicates that the structure 1a assigned to margolone is not correct and it needs to be reinvestigated.
