89329-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89329-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,2 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89329-17:
(7*8)+(6*9)+(5*3)+(4*2)+(3*9)+(2*1)+(1*7)=169
169 % 10 = 9
So 89329-17-9 is a valid CAS Registry Number.

REACTIVITY OF ARYLCINNAMATES IN POLYPHOSPHORIC ACID (PPA): CYCLISATION AND REARRANGEMENT REACTIONS
Dupin, Jean-Francois E.,Chenault, Jacques
, p. 2401 - 2404 (2007/10/02)
In polyphosphoric acid (PPA), various phenyl-substituted cinnamates react to give 4-phenyl-3,4-dihydrocoumarins, flavanones or 3-phenylindanone owing to the nature of the substituents on the phenyl moiety.
