Check Digit Verification of cas no
The CAS Registry Mumber 20411-84-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,1 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20411-84:
(7*2)+(6*0)+(5*4)+(4*1)+(3*1)+(2*8)+(1*4)=61
61 % 10 = 1
So 20411-84-1 is a valid CAS Registry Number.

Fluorine-Containing Organozinc Reagents. Part I. A Simple Synthesis of 2,2-Dichloro-3,3,3-trifluoropropanol
Lang, Robert Werner
, p. 881 - 886 (2007/10/02)
The title compound 1, which can be regarded as synthetic equivalent of substituted 1,1,1-trifluoroacetone 2, is prepared by Zn-induced reductive addition of 1,1,1-trichloro-2,2,2-trifluoroethane (3) to formaldehyde (4).A brief survey of the scope of this C-C-bond formation leading to a variety of new CF3-containing synthetic building blocks is also given.
