Check Digit Verification of cas no

The CAS Registry Mumber 674819-29-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,4,8,1 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 674819-29:
(8*6)+(7*7)+(6*4)+(5*8)+(4*1)+(3*9)+(2*2)+(1*9)=205
205 % 10 = 5
So 674819-29-5 is a valid CAS Registry Number.

Synthesis of new thiophene and benzo[b]thiophene hydrazide derivatives as human NPY Y5 antagonists

Galiano, Silvia,Erviti, Oihana,Perez, Silvia,Moreno, Antonio,Juanenea, Laura,Aldana, Ignacio,Monge, Antonio

, p. 597 - 599 (2004)

Neuropeptide Y is one of the most potent appetite stimulating hormones known. Novel thiophene and benzo[b]thiophene hydrazide derivatives were synthetized and evaluated biologically as NPY Y1 and Y5 receptor subtype antagonists. They were found to have nanomolar binding affinities for human NPY Y5 receptor, obtaining the lead compound, trans-N-4-[N′-(thiophene-2-carbonyl)hydrazinocarbonyl]cyclohexylmethyl-4- bromobenzenesulfonamide, which binds with a 7.70 nM IC50 to the hY5 receptor.
