Check Digit Verification of cas no

The CAS Registry Mumber 212191-01-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,1,9 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 212191-01:
(8*2)+(7*1)+(6*2)+(5*1)+(4*9)+(3*1)+(2*0)+(1*1)=80
80 % 10 = 0
So 212191-01-0 is a valid CAS Registry Number.

LINK synthesis with 3-hydroxy-1H-pyrazoles: 3-carboxyisoalkyloxy-1H-pyrazoles-bicyclic acylpyrazolium salts and γ-lactams-3-carboxyisoalkyloxy-4,5-dihydro-1H-pyrazol-5-ones

Dorn, Helmut,Ozegowski, Ruediger

, p. 437 - 449 (2007/10/03)

1-Substituted 3-hydroxy-1H-pyrazoles 1 react with chloroform, NaOH, and aceton resp. butan-2-one O-regiospecifically to yield 2-methyl-2-[(1H-pyrazol-3-yl)oxy]-propanoic resp. -butanoic acids 14 via a dichlorocarbene (12)-dichlorooxirane (9) pathway. Chlorides 17 of 14 easily cyclize to N-acylpyrazolium salts 18/19, which quantitatively afford esters 22-26 and amides 27-29 of 14. Enantiomers of the butanoic acid 14h, obtained via their diastereomeric cholesterol esters, differ in their stimulus to peroxisome proliferation. At 140°C pyrazolium salts 18 undergo thermolysis to bicyclic β-oxa-γ-lactams 30-32. 3-Carboxyisoalkylamino-pyrazoles similarly give 1H-β-aza-γ-lactams 34. Reactions of 14 with surplus SOCl2 result in 6-chloro-37 resp. 7-chloro-β-oxa-γ-lactams 38 via chlorosulfinylation and extrusion of SO, and in 4,4-bispyrazolyl-sulfoxide 39. A mild introduction of additional O-functions into pyrazoles affording 4,5-dihydro-3-hydroxy-5-oxo-1H-pyrazoles 52-57 is presented. Biological effects of the new pyrazoles are protection against shock and ADP-induced thromboembolism, reduction of serum lipids and improvement of blood flow. Johann Ambrosius Barth 1998.
