Check Digit Verification of cas no

The CAS Registry Mumber 98482-56-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,8 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 98482-56:
(7*9)+(6*8)+(5*4)+(4*8)+(3*2)+(2*5)+(1*6)=185
185 % 10 = 5
So 98482-56-5 is a valid CAS Registry Number.

Stereochemical Assignments for 1-Phenyl-1,2,3-butanetrione 2-Oxime and Related Compounds

Hansen, John F.,Flippen-Anderson, Judith L.

, p. 3955 - 3956 (1985)

The 2-oximes of 3-methyl,3-ethyl, and 3-isopropyl-1-phenyl-1,2,3-propanetrione formed by nitrosation of the β-diketones exist preferentially in the Z configuration.For 3-tert-butyl-1-phenyl-1,2,3-propanetrione 2-oxime the (E)- and (Z)- oximes are formed in nearly equal amounts.An explanation for the steric effect of the tert-butyl group is suggested.
