102222-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102222-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,2,2 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 102222-55:
(8*1)+(7*0)+(6*2)+(5*2)+(4*2)+(3*2)+(2*5)+(1*5)=59
59 % 10 = 9
So 102222-55-9 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.
