Check Digit Verification of cas no
The CAS Registry Mumber 69657-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,6,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69657-20:
(7*6)+(6*9)+(5*6)+(4*5)+(3*7)+(2*2)+(1*0)=171
171 % 10 = 1
So 69657-20-1 is a valid CAS Registry Number.

Arene-Catalysed Lithiation of 1,4-Dichlorobut-2-enes and 3,4-Dichlorobut-1-ene and Reaction with Electrophiles: A Common Reaction Pathway
Guijarro, Albert,Yus, Miguel
, p. 7857 - 7864 (1994)
The reaction of (Z) or (E)-1,4-dichlorobut-2-ene (1, 2), or 3,4-dichlorobut-1-ene (3) with an excess of lithium powder and a catalytic amount of 4,4'-di-tert-butylbiphenyl (5 molpercent) in the presence of an electrophile tCHO, Me3SiCl> in THF at 0 deg C yields, after hydrolysis, the corresponding 1,4- and 1,2-disubstituted compounds (Z/E)-4 and 5, the ratio of them being independent on the starting material.In the case of compounds 4 the Z-diastereomer is largely the major one.When dichlorodiethylsilane was used as electrophile the corresponding substituted silacyclopentene 6 was the only reaction product isolated.A possible mechanism involving dilithiated species is proposed.
