General Description
cis,cis-Mucononitrile (Z,Z-2,4-hexadienedinitrile) can be prepared by the copper-catalyzed oxidation of o-phenylenediamine. 13C MAS NMR spectra of cis,cis-mucononitrile oriented in liquid-crystalline media has been studied. Pt-catalyzed addition of diethylphosphine to cis,cis-mucononitrile yields the new diphosphine, Et2PCH(CN)CH(CH2CH2CN)PEt2.
Check Digit Verification of cas no
The CAS Registry Mumber 1557-59-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1557-59:
(6*1)+(5*5)+(4*5)+(3*7)+(2*5)+(1*9)=91
91 % 10 = 1
So 1557-59-1 is a valid CAS Registry Number.

Hypervalent iodine(iii)-induced oxidative [4+2] annulation of o-phenylenediamines and electron-deficient alkynes under metal-free conditions has been developed. The reaction allows for direct access to quinoxalines bearing two electron-withdrawing groups in an efficient manner.
