Check Digit Verification of cas no

The CAS Registry Mumber 98239-49-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,3 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98239-49:
(7*9)+(6*8)+(5*2)+(4*3)+(3*9)+(2*4)+(1*9)=177
177 % 10 = 7
So 98239-49-7 is a valid CAS Registry Number.

Chemistry of Heterocylces: Part VIII - Synthesis of Isoxazolylethylpyrazoles

Reddi, K. Malla,Rao, C. Janakirama,Murthy, A. Krishna

, p. 212 - 213 (2007/10/02)

The base-catalysed addition of acetylacetone to 3-methyl-4-nitro-5-styrylisoxazoles (II) leads to the Michael adducts 3-pentane-2,4-diones (III).These β-diketones (III) undergo cyclization with hydrazine sulphate and phenylhydrazine to furnish pyrazoles (IV) and N-phenylpyrazoles (V), respectively.
