87797-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87797-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,9 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87797-20:
(7*8)+(6*7)+(5*7)+(4*9)+(3*7)+(2*2)+(1*0)=194
194 % 10 = 4
So 87797-20-4 is a valid CAS Registry Number.

An approach to the biomimetic synthesis of aryltetralin lignans
Pelter, Andrew,Ward, Robert S.,Rao, Ramohan R.
, p. 2933 - 2938 (2007/10/02)
The BF3 catalysed cyclisation of 3-arylpropyl substituted quinone-methide ketals affords a mild, biomimetic route to aryltetralins. 1H- and 13C-NMR spectra of the products are reported.
