60144-50-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 60144-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,1,4 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 60144-50:
(7*6)+(6*0)+(5*1)+(4*4)+(3*4)+(2*5)+(1*0)=85
85 % 10 = 5
So 60144-50-5 is a valid CAS Registry Number.

A Second Synthesis of 6>(1,2,3,4,5,6)Cyclophane (Superphane)
El-tamany, Sayed,Hopf, Henning
, p. 1682 - 1685 (2007/10/02)
Starting with 4,5,12,13-tetramethylparacyclophane (1) a novel synthesis of 6>(1,2,3,4,5,6)cyclophane (6) has been achieved.Decisive prerequisite for the success of the six-step reaction sequence is the observation, that 1 may be formylated in the first reaction step to the dialdehydes 4 and 5.
