139029-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139029-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,2 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139029-48:
(8*1)+(7*3)+(6*9)+(5*0)+(4*2)+(3*9)+(2*4)+(1*8)=134
134 % 10 = 4
So 139029-48-4 is a valid CAS Registry Number.

ON THE APPLICATION OF NOE DIFFERENCE SPECTROSCOPY FOR SPECTRAL AND STRUCTURAL ASSIGNMENTS WITH SUBSTITUTED 1,2,3-TRIAZOLES
Holzer, Wolfgang
, p. 9783 - 9792 (1991)
The application of NOE difference spectroscopy for the unambiguous discrimination between signals of H-4 and H-5 in 1-substituted 1H-1,2,3-triazoles as well as for the differentiation between regioisomeric 1,4-, 1,5- and 2,4-disubstituted 1,2,3-triazoles
