948830-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 948830-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,8,8,3 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 948830-20:
(8*9)+(7*4)+(6*8)+(5*8)+(4*3)+(3*0)+(2*2)+(1*0)=204
204 % 10 = 4
So 948830-20-4 is a valid CAS Registry Number.

A new strategy for the synthesis of optically active benzylic fluorides and corresponding five-membered heteroaromatic analogues
Grée, Danielle,Grée, René
, p. 5435 - 5438 (2008/02/10)
Benzylic fluorides, as well as five-membered heterocycles, have been obtained in high ee's through cycloaddition reactions starting from easily accessible optically active propargylic fluorides.
