Check Digit Verification of cas no

The CAS Registry Mumber 1223515-79-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,3,5,1 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1223515-79:
(9*1)+(8*2)+(7*2)+(6*3)+(5*5)+(4*1)+(3*5)+(2*7)+(1*9)=124
124 % 10 = 4
So 1223515-79-4 is a valid CAS Registry Number.

Synthesis and antimicrobial activity of novel pyrazolo[3,4-d]pyrimidin derivatives

Khobragade, Chandrahas N.,Bodade, Ragini G.,Konda, Shankaraiah G.,Dawane, Bhaskar S.,Manwar, Anand V.

experimental part, p. 1635 - 1638 (2010/06/14)

Pyrazolo[3,4-d]thiazolo[3,2-a]pyrimidin-4-one derivatives have been prepared by cyclocondensation of ethyl 2-cyano-3,3-bis(methylthio)prop-2-enoate with 2-amino-4-(substitutedphenyl)thiazole to give 3-cyano-2-methylthio-4-oxo-4H-6-(substitutedphenyl)thiazolo[3,2-a]pyrimidin (2a-j) and further reacting with hydrazine hydrate to yield the target compounds (3a-j). The chemical structure of the compounds was confirmed by IR and 1H NMR spectral data. All the compounds of the series have been screened for their antibacterial and antifungal activity studies. The result revealed that all compounds showed significant antimicrobial activity.
