Check Digit Verification of cas no

The CAS Registry Mumber 153562-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,5,6 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 153562-20:
(8*1)+(7*5)+(6*3)+(5*5)+(4*6)+(3*2)+(2*2)+(1*0)=120
120 % 10 = 0
So 153562-20-0 is a valid CAS Registry Number.

Investigation on the reactions of fluorinated 1,3-diketones with 5-aminotetrazole: Synthesis of some tetrazolopyrimidines and β-ketoamine derivatives

Joshi, Krishna C.,Dandia, Anshu,Jain, Sunita,Joshi, Rahul

, p. 886 - 888 (2007/10/02)

Reactions of 5-aminotetrazole (II) with fluorinated 1,3-diketones (Ia-c) in different media have been investigated and found to be solvent dependent.Tetrazolopyrimidines (IIIa-c) are exclusively obtained in gl. acetic acid while β-ketoamines (Va-c) of tetrazole along with IIIa-c are obtained in abs. ethanol.The spectral data of the free schiff bases indicate that the site of amine condensation in unsymmetrical β-ketoamines is the lesser enolized acyl oxygen and the ketoamino-form is the predominant tautometer.The proposed structures are fully corroborated by IR, PMR, 19F NMR and mass spectral data.
