Check Digit Verification of cas no

The CAS Registry Mumber 188296-54-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,2,9 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 188296-54:
(8*1)+(7*8)+(6*8)+(5*2)+(4*9)+(3*6)+(2*5)+(1*4)=190
190 % 10 = 0
So 188296-54-0 is a valid CAS Registry Number.

A general approach to substituted diphenyldiazenes

Lutz, Toni A.,Spanner, Patrick,Wanner, Klaus T.

, p. 1579 - 1589 (2016/03/01)

A general and practical synthetic method for the construction of unsymmetrically substituted diphenyldiazenes based on classical azo coupling reaction has been developed. A key feature of this method is the use of N,N-diallyl protected aniline derivatives

Assisted tandem catalytic RCM-aromatization in the synthesis of pyrroles and furans

Schmidt, Bernd,Krehl, Stefan,Jablowski, Eric

supporting information; experimental part, p. 5119 - 5130 (2012/08/07)

An assisted tandem catalytic transformation of diallyl amines and diallyl ethers into N-aryl pyrroles and furans, respectively, is described. The sequence relies on ring closing metathesis followed by dehydrogenation of the initially formed dihydropyrroles and dihydrofurans. Both steps are Ru-catalyzed, but the sequence requires only one precatalyst, because conversion of the metathesis catalyst into the dehydrogenation catalyst is achieved in situ, triggered by the oxidant tert-butyl hydroperoxide.
