Check Digit Verification of cas no

The CAS Registry Mumber 844842-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,8,4 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 844842-31:
(8*8)+(7*4)+(6*4)+(5*8)+(4*4)+(3*2)+(2*3)+(1*1)=185
185 % 10 = 5
So 844842-31-5 is a valid CAS Registry Number.

Synthesis, magnetic and spectral studies of some novel binuclear dioxomolybdenum(VI) chelates involving Schiff bases derived from sulpha drugs and 4-benzoyl-3-methyl-1-phenyl-2-pyrazolin-5-one

Maurya,Pandey,Sutradhar

, p. 763 - 768 (2007/10/03)

This paper reports the synthesis of six new binuclear dioxomolybdenum(VI) complexes of the composition [{MoO2(OH)2} 2(L)2], where L = N-(4′-benzoylidene-3′ -methyl-1′-phenyl-2′-pyrazoline-5′-one)sulphamethoxazole (HL1), N-(4′-benzoylidene-3′-methyl-1′ -phenyl-2′-pyrazoline-5′-one)sulphadimidine (HL2), N-(4′-benzoylidene -3′-methyl-1′-phenyl-2′ -pyrazoline-5′-one)sulphadiazine (HL3); N-(4′ -benzoylidene-3′-methyl-1′-phenyl-2′-pyrazoline-5′-ne) -sulphanilamide (HL4), N-(4′-benzoylidene-3′ -methyl-1′-phenyl-2′-pyrazoline-5′-) sulphamerazine (HL 5) or N-(4′-benzoylidene-3′-methyl-1′ -phenyl-2′-pyrazoline-5′-one)sulphadimethoxine (HL6). These complexes have been obtained by the interaction of bis(acetylacetonato)-dioxomolybdenum(VI) with the said ligands in ethanol. All these complexes have been characterized by elemental analysis, molar conductance, decomposition temperature and magnetic measurements, 1HNMR, IR and electronic spectral studies.
