157835-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157835-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,8,3 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 157835-78:
(8*1)+(7*5)+(6*7)+(5*8)+(4*3)+(3*5)+(2*7)+(1*8)=174
174 % 10 = 4
So 157835-78-4 is a valid CAS Registry Number.

Revolveneynes: Novel eneyneparacyclophanes by sequential palladium coupling
Romero, Miguel A.,Fallis, Alex G.
, p. 4711 - 4714 (2007/10/02)
The synthesis and initial study of a new series of eneyne-bridged cyclophanes (revolveneynes) are described in which the phenyl rings are free to rotate within the cavity. Either palladium coupling or oxidative dimerization provided rapid access to [14],
