Check Digit Verification of cas no
The CAS Registry Mumber 77128-35-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,2 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77128-35:
(7*7)+(6*7)+(5*1)+(4*2)+(3*8)+(2*3)+(1*5)=139
139 % 10 = 9
So 77128-35-9 is a valid CAS Registry Number.

Treatment of 4-(1-nitro-2-oxocyclododec-1-yl)butanal (1) and of its methyl derivative 5 with pentylamine in EtOH at room temperature gave the ring-enlarged aminomethylidene derivatives 6 and 7, respectively (Scheme 1).After hydrolysis of the aminomethylidene group in 6 and 7 and deformylation followed by a reductive Nef-type reaction, the macrocyclic diketones 10 and 11, respectively, were obtained.They were transformed by a modified Hantzsch procedure to the title compound (+/-)-muscopyridine (13) and normuscopyridine (12), respectively.
