137389-53-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137389-53-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,8 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137389-53:
(8*1)+(7*3)+(6*7)+(5*3)+(4*8)+(3*9)+(2*5)+(1*3)=158
158 % 10 = 8
So 137389-53-8 is a valid CAS Registry Number.

SYNTHESIS OF A TETRAIMIDAZOLE CONTAINING MACROCYCLE: A NEW LIGAND CLASS
Street, J. Paul
, p. 3333 - 3336 (2007/10/02)
The first member of a new imidazole containing macrocycle, (2), has been prepared and spectrally characterized.Macrocyclization is achieved concurrently with imidazole ring construction, utilizing the parent reaction of benzylamines with 2-oximino-1,3-dicarbonyl compounds.
