1581-17-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1581-17-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,8 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1581-17:
(6*1)+(5*5)+(4*8)+(3*1)+(2*1)+(1*7)=75
75 % 10 = 5
So 1581-17-5 is a valid CAS Registry Number.

Studies on UV/Vis Absorption Spectra of Azo Dyes. XVIII. Substituent Effects on the Absorption Maxima of the n-->?* and ?-->?* Bands of 4-N,N-Diethylaminoazobenzenes

Haessner, Carmen,Mustroph, H.

, p. 493 - 498 (2007/10/02)

The spectra of 27 substituted 4-N,N-diethylaminoazobenzenes are determined.The band system can be separated by deconvolution into two Gaussian curves.The results so obtained show that the effects of substituents on n-->?* and ?-->?* transitions are similar and that electron withdrawing substituents in the phenylazo residue cause a bathochromic shift of both the n-->?* and the ?-->?* bands.
