Check Digit Verification of cas no

The CAS Registry Mumber 75328-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,3,2 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75328-80:
(7*7)+(6*5)+(5*3)+(4*2)+(3*8)+(2*8)+(1*0)=142
142 % 10 = 2
So 75328-80-2 is a valid CAS Registry Number.

Reaction of 3-Iodoflavanones with Hydrazine Hydrate & Phenylhydrazine: Synthesis of Pyrazoles

Joshi, M. G.,Wadokar, K. N.

, p. 1089 - 1090 (2007/10/02)

3-Iodoflavanones (IIa-d), obtained from 2'-hydroxy-4-methoxychalkones and ICl in acetic acid, when reacted with N2H4 * H2O in ethanol at room temperature give 3,5-diarylpyrazoles (IIIa-d) while with C6H5NH-NH2 * HCl in pyridine, 3,5-diaryl-1-phenylpyrazoles (IVa-d) are obtained.The identity of III and IV has been confirmed by independent and unambiguous synthesis of these pyrazoles from 2-hydroxydibenzoylmethanes.
