6624-51-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6624-51-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,2 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6624-51:
(6*6)+(5*6)+(4*2)+(3*4)+(2*5)+(1*1)=97
97 % 10 = 7
So 6624-51-7 is a valid CAS Registry Number.

Novel transition-metal complexes of camphorquinone dioxime ligands
Ma, Man Sheung,Angelici, Robert J.
, p. 363 - 370 (2008/10/08)
Camphorquinone dioxime, H2CQD, is known to exist in four isomeric forms (α, β, γ, and δ) which differ by the orientations of the OH groups on their oxime nitrogen atoms. The deprotonated β-HCQD- coordinates via the two N atoms to for
