89683-64-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89683-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,8 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89683-64:
(7*8)+(6*9)+(5*6)+(4*8)+(3*3)+(2*6)+(1*4)=197
197 % 10 = 7
So 89683-64-7 is a valid CAS Registry Number.

NICKEL(O)-KATALYSIERTE CYCLOADDITIONEN VON (DIORGANYLMETHYLEN)CYCLOPROPANEN MIT ELEKTRONENARMEN OLEFINEN
Binger, Paul,Wedemann, Petra
, p. 5847 - 5850 (2007/10/02)
Cycloadditions of (diorganylmethylene)cyclopropanes (R = Ph; CH3) with electron-deficient olefins are catalyzed by trisarylphosphite - Ni(O)-compounds to give (diorganylmethylene)cyclopentane derivatives in high yields.
