Check Digit Verification of cas no
The CAS Registry Mumber 1682-04-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,8 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1682-04:
(6*1)+(5*6)+(4*8)+(3*2)+(2*0)+(1*4)=78
78 % 10 = 8
So 1682-04-8 is a valid CAS Registry Number.

Regiospecific Syn Addition of (Polyfluoroaryl)copper Reagents to Fluorinated Acetylenes: Preparation and Subsequent Functionalization of Internal Vinylcopper Reagents
MacNeil, Kathryn J.,Burton, Donald J.
, p. 4411 - 4417 (1993)
(Pentafluorophenyl)copper (C6F5Cu) can be prepared from a metathesis reaction between C6F5CdX (X = Br or C6F5) and CuY (Y = Cl or Br).The arylcopper reagent undergoes a stereo- and regiospecific syn addition to fluorinated alkynes, which results in the corresponding internal alkenylcopper intermediate.This vinylcopper reagent can be subsequently functionalized with a variety of electrophiles, including aryl, alkyl, allyl, and acyl halides, to afford tetrasubstituted fluoroalkenes.The para-substituted arylcopper analogs also successfully undergo the addition reaction.
