Check Digit Verification of cas no

The CAS Registry Mumber 90648-07-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,4 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90648-07:
(7*9)+(6*0)+(5*6)+(4*4)+(3*8)+(2*0)+(1*7)=140
140 % 10 = 0
So 90648-07-0 is a valid CAS Registry Number.

Influence of Ortho Substituents on UV Spectra of Aryl Methyl Sulphoxides

Baliah, V.,Varadachari, R.

, p. 116 - 119 (2007/10/02)

The UV spectra of some ortho substituted aryl methyl sulphoxides are recorded and analysed.A comparison of the steric effects of ortho substituents on conjugation of CH3S(-), CH3SO(-) and CH3SO2(-) groups with the para substituents in the benzene ring has been made.The ortho substituents do not inhibit conjugation in the case of sulphones while they cause a marked inhibition in the case of sulphides and sulphoxides.The inhibition of conjugation of the CH3SO(-) group under the influence of ortho substituents is observed when the CH3SO(-) group acts both as an electron donor and as an electron acceptor.An explanation is offered for the observed steric effects.
