153442-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153442-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,4,4 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 153442-06:
(8*1)+(7*5)+(6*3)+(5*4)+(4*4)+(3*2)+(2*0)+(1*6)=109
109 % 10 = 9
So 153442-06-9 is a valid CAS Registry Number.

A Concise Synthesis of Enantiomerically Pure Taxane C-Ring via the Wittig Rearrangement
Kress, Michael H.,Kaller, Brian F.,Kishi, Yoshito
, p. 8047 - 8050 (2007/10/02)
An efficient, stereoselective synthesis of an enantiomerically pure C-ring precursor 14-S of O-cinnamoyltaxicins-I and -II has been achieved from 3-methyl-2-cyclohexen-1-ol, using a Wittig rearrangement as the key step.
