39877-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39877-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,8,7 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39877-89:
(7*3)+(6*9)+(5*8)+(4*7)+(3*7)+(2*8)+(1*9)=189
189 % 10 = 9
So 39877-89-9 is a valid CAS Registry Number.

A new highly asymmetric chelation-controlled heck arylation
Nilsson, Peter,Larhed, Mats,Hallberg, Anders
, p. 3430 - 3431 (2007/10/03)
This communication describes the development of a new highly asymmetric chelation-controlled Heck arylation. The methodology permits formation of 2-aryl-2-methyl cyclopentanones in good to very good two-step yields (45-78%) with excellent chiral enrichmen
