83755-85-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83755-85-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,5 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83755-85:
(7*8)+(6*3)+(5*7)+(4*5)+(3*5)+(2*8)+(1*5)=165
165 % 10 = 5
So 83755-85-5 is a valid CAS Registry Number.

Configuration-sensitive infrared bands and vibrational assignments of S-alkyldithizones based on isotopic substitutions

Yamada, Osamu,Hiura, Hidehumi,Igarashi, Takashi,Kaneko, Norio,Takahashi, Hiroaki

, p. 1409 - 1416 (2007/10/02)

By comparison of the infrared spectra of S-methyl-, S-ethyl- and S-isopropyldithizones in the solid state, the configuration-sensitive i.r. bands have been obtained for the trans-syn-s-trans and trans-anti-s-trans configurations with respect to the N=N, C=N and C-N bonds of the formazan skeleton.The vibrational assignment of S-methyldithizone has been made based on the frequency shifts on isotopic substitutions: 1,5-15N and 2,4-15N- substitutions, deuterium substitutions of the methyl group, phenyl groups and N-H group, and deuterium substitutions of both phenyl and N-H groups.
