159928-90-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159928-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,9,2 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 159928-90:
(8*1)+(7*5)+(6*9)+(5*9)+(4*2)+(3*8)+(2*9)+(1*0)=192
192 % 10 = 2
So 159928-90-2 is a valid CAS Registry Number.

New carbon radical chemistry as a model for the biogenesis of the interiorin/kadsulignan type of dibenzocyclooctadiene lignan
Green, Stuart P.,Whiting, Donald A.
, p. 193 - 201 (2007/10/03)
Novel intramolecular radical spirocyclisation reactions in aromatic nuclei, 48→49, 40→22 and 34→32, are presented, which mimic a key step in the proposed biosynthesis of the interiorins 2a-d, the kadsulignans 3a,b and relatives.
