65887-64-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65887-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,8 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 65887-64:
(7*6)+(6*5)+(5*8)+(4*8)+(3*7)+(2*6)+(1*4)=181
181 % 10 = 1
So 65887-64-1 is a valid CAS Registry Number.

Synthesis of biaryls by intramolecular radical transfer in phosphinates
Clive,Kang
, p. 6083 - 6091 (2007/10/03)
Phosphinates 20a-35a give biaryls 20b-35b on heating with stannanes in the presence of AIBN. The process involves a radical ipso substitution on the migrating aryl ring.
