Check Digit Verification of cas no

The CAS Registry Mumber 389635-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,9,6,3 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 389635-01:
(8*3)+(7*8)+(6*9)+(5*6)+(4*3)+(3*5)+(2*0)+(1*1)=192
192 % 10 = 2
So 389635-01-2 is a valid CAS Registry Number.

A rapid access to biaryl ether containing macrocycles by pairwise use of Ugi 4CR and intramolecular S(N)Ar-based cycloetherification.

Cristau,Vors,Zhu

, p. 4079 - 4082 (2007/10/03)

[reaction: see text] From readily accessible starting materials, macrocycles with an endo aryl-aryl ether bond are synthesized in only two operations by combination of the Ugi four-component reaction and an intramolecular S(N)Ar reaction. The nitro group serves as an activator for the macrocyclization and provides a handle for the introduction of functional group diversity. A Ugi reaction promoted by ammonium chloride in aprotic solvent is documented for the first time.
