Check Digit Verification of cas no

The CAS Registry Mumber 16904-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,0 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16904-20:
(7*1)+(6*6)+(5*9)+(4*0)+(3*4)+(2*2)+(1*0)=104
104 % 10 = 4
So 16904-20-4 is a valid CAS Registry Number.

The dipole moments of cis- and trans-trichlorotriaquoruthenium(III)

Mercer,McAllivster

, p. 1414 - 1416 (2008/10/08)

The dipole moments of cis- and trans-trichlorotriaquoruthenium(III) have been found to be 7.5 and 4.4 D., respectively. The measurements were made at -78.5°, using ethyl acetate as a solvent. On the basis of the dipole moments, the assignment of the trans configuration to the isomer which elutes first from an anion-exchange column was confirmed.
