Check Digit Verification of cas no
The CAS Registry Mumber 199682-75-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,6,8 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 199682-75:
(8*1)+(7*9)+(6*9)+(5*6)+(4*8)+(3*2)+(2*7)+(1*5)=212
212 % 10 = 2
So 199682-75-2 is a valid CAS Registry Number.

Vilsmeier formylation of hydrazones and semicarbazones derived from alkyl, benzyl, and cycloalkyl methyl ketones
Lebedev,Lebedeva,Sheludyakov,Kovaleva,Ustinova,Kozhevnikov
, p. 412 - 416 (2007/10/03)
Formylation of ten accessible phenylhydrazones and semicarbazones derived from alkyl, benzyl, and cycloalkyl methyl ketones with the complex of POCl 3 with dimethylformamide was studied. Depending on the electronic and steric structure of the substrates, the reaction yields 1-phenyl- or 1-unsubstituted 3,4-dialkyl-, 3-alkyl-4-aryl-, or 3-alkyl-4-formylpyrazoles. These compounds can be readily oxidized into the corresponding carboxylic acids. 2005 Pleiades Publishing, Inc.
