121565-40-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121565-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,6 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121565-40:
(8*1)+(7*2)+(6*1)+(5*5)+(4*6)+(3*5)+(2*4)+(1*0)=100
100 % 10 = 0
So 121565-40-0 is a valid CAS Registry Number.

Claisen Rearrangement of Some 7-Cinnamyloxychromones
Jain, A. C.,Gupta, R. K.,Chawla, Chitwan
, p. 1032 - 1034 (2007/10/02)
The 7-cinnamyloxychromones (2a, 2b and 7) undergo Claisen rearrangement in refluxing N,N-dimethylaniline to give 8-(1-phenyl-2-propenyl) derivatives (4a, 4d and 8 respectively) as normal products in good yields.These have features similar to those of natu
