Check Digit Verification of cas no

The CAS Registry Mumber 1246997-80-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,9,9 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1246997-80:
(9*1)+(8*2)+(7*4)+(6*6)+(5*9)+(4*9)+(3*7)+(2*8)+(1*0)=207
207 % 10 = 7
So 1246997-80-7 is a valid CAS Registry Number.

An expedient synthesis of indolo[1,2-a]quinolines via Mn(OAc)3-mediated oxidative free radical cyclization and NaI/O2-assisted dealkoxycarbonylation/ aerobic oxidation cascade

Lee, Hyun Seung,Kim, Se Hee,Kim, Yu Mi,Kim, Jae Nyoung

scheme or table, p. 5071 - 5075 (2011/01/04)

An expedient synthetic procedure of indolo[1,2-a]quinolines was developed using a sequential Cu-mediated N-arylation of indole, Mn(OAc) 3-mediated oxidative free radical cyclization, and NaI/O 2-assisted concomitant dealkoxycarbonylation/aerobic oxidation. The last step was replaced by a palladium-catalyzed decarboxylation/elimination protocol for the allyl ester derivatives.
