Check Digit Verification of cas no

The CAS Registry Mumber 1418129-51-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,8,1,2 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1418129-51:
(9*1)+(8*4)+(7*1)+(6*8)+(5*1)+(4*2)+(3*9)+(2*5)+(1*1)=147
147 % 10 = 7
So 1418129-51-7 is a valid CAS Registry Number.

Synthetic approach for constructing the 1-oxygenated carbazole core and its application to the preparation of natural alkaloids

Bautista, Rafael,Jerezano, Alberto V.,Tamariz, Joaquin

, p. 3327 - 3336,10 (2012/12/11)

An efficient synthetic approach for the construction of the 1-oxygenated carbazole core is described. The condensation of cyclohexane-1,2-diones with a series of anilines yielded the corresponding 2-anilinocyclohex-2-en-1-ones, followed by the one-pot aromatization/methylation process of the latter to provide N-aryl-2-methoxyanilines. A palladium(II)-catalyzed cyclization of these N-aryl-2-methoxyanilines afforded the desired 1-methoxycarbazole frame in high overall yields. This protocol was implemented for the total synthesis of the naturally occurring glycozolicine and 6-methoxymurrayanine.
