Check Digit Verification of cas no

The CAS Registry Mumber 220875-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,8,7 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 220875-50:
(8*2)+(7*2)+(6*0)+(5*8)+(4*7)+(3*5)+(2*5)+(1*0)=123
123 % 10 = 3
So 220875-50-3 is a valid CAS Registry Number.

Synthesis and reactions of 1-(2-pyridyl)-3-methyl-4-chloro-5-formyl-6,7-dihydroindazoles

Strakova,Delyatitskaya,Petrova,Strakov

, p. 669 - 673 (1998)

The Vilsmeier formylation of 1-(2-pyridyl)-3-methyl-4-oxo-4,5,6,7-tetrahydroindazole and its 6-phenyl derivative gives 1-(2-pyridyl)-3-methyl-4-chloro-5-formyl-6,7-dihydroindazoles. Reactions of these derivatives with different N- and C-nudeophilic agents, including bisnucleophiles, were studied as a means of obtaining new 4- and 5-functional derivatives of indazole and its condensed systems. 1998 Plenum Publishing Corporation.
