Check Digit Verification of cas no
The CAS Registry Mumber 101689-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,6,8 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 101689-22:
(8*1)+(7*0)+(6*1)+(5*6)+(4*8)+(3*9)+(2*2)+(1*2)=109
109 % 10 = 9
So 101689-22-9 is a valid CAS Registry Number.

Synthesis of Malabaricone-A - Confirmation of its Structure
Parthasarathy, M. R.,Gupta, Sushma
, p. 965 (2007/10/02)
Wittig reaction of 7-phenylheptyl bromide (I) with 2,6-dimethoxyphenylglyoxal (II) affords 1-(2,6-dimethoxybenzoyl)-8-phenyl-oct-1-ene (III).III on hydrogenation over Pd/C catalyst followed by demethylation with pyridine hydrobromide yields malabaricone-A
