Check Digit Verification of cas no

The CAS Registry Mumber 18781-55-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,8 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18781-55:
(7*1)+(6*8)+(5*7)+(4*8)+(3*1)+(2*5)+(1*5)=140
140 % 10 = 0
So 18781-55-0 is a valid CAS Registry Number.

N-indolyltriethylborate: A useful reagent for synthesis of C3-quaternary indolenines

Lin, Aijun,Yang, Jiong,Hashim, Mohamed

supporting information, p. 1950 - 1953 (2013/06/04)

N-Indolyltriethylborate was found to be a useful reagent for dearomatizing C3-alkylation of 3-substituted indoles with both activated and nonactivated alkyl halides to give C3-quaternary indolenines, pyrroloindolines, furoindoline, and hexahydropyridoindoline under mild reaction conditions. The utility of these reagents was demonstrated in the syntheses of a pyrroloindoline-4- cholestene hybrid and debromoflustramine B.

Palladium catalyzed decarboxylative rearrangement of N-alloc indoles

Chen, Jun,Cook, Matthew J.

supporting information, p. 1088 - 1091 (2013/04/10)

A highly efficient palladium catalyzed decarboxylative allylic rearrangement of alloc indoles has been developed. This can also be combined with a Suzuki-Miyaura cross-coupling reaction in a single pot transformation. Substituted alloc groups and benzylic variants have also been demonstrated alongside promising initial results on the enantioselective variant.
