685570-02-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 685570-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,5,5,7 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 685570-02:
(8*6)+(7*8)+(6*5)+(5*5)+(4*7)+(3*0)+(2*0)+(1*2)=189
189 % 10 = 9
So 685570-02-9 is a valid CAS Registry Number.

3-Iodoselenophene derivatives: a versatile substrate for Negishi cross-coupling reaction

Schumacher, Ricardo F.,Alves, Diego,Brand?o, Ricardo,Nogueira, Cristina W.,Zeni, Gilson

, p. 538 - 542 (2008)

3-Iodoselenophene derivatives undergo a direct Negishi cross-coupling reaction with several organozinc compounds in the presence of a catalytic amount of Pd(PPh3)4 in THF at room temperature. This cross-coupling reaction proceeded cl

Alves, Diego,Luchese, Cristiane,Nogueira, Cristina W.,Zeni, Gilson

, p. 6726 - 6734 (2008/02/11)

(Chemical Equation Presented) We present here our results of the electrophilic cyclization reaction of (Z)-selenoenynes with different electrophiles such as I2, ICl, PhSeBr, and PhSeCl. The cyclization reaction proceeded cleanly under mild reac

, p. 1135 - 1138 (2007/10/03)

Vinylic selenides were prepared in good yields by hydroselenation of alkynes with lithium butylselenolate generated by reaction of n-butyllithium with elemental selenium. The regio- and stereochemistry of the hydroselenation depend on the nature of the su
