Check Digit Verification of cas no

The CAS Registry Mumber 1263146-01-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,1,4 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1263146-01:
(9*1)+(8*2)+(7*6)+(6*3)+(5*1)+(4*4)+(3*6)+(2*0)+(1*1)=125
125 % 10 = 5
So 1263146-01-5 is a valid CAS Registry Number.

Chemoselective cascade synthesis of N-fused heterocycles via silver(I) triflate-catalyzed friedel-crafts/N-C bond formation sequence

Hao, Lu,Pan, Yingming,Wang, Tao,Lin, Min,Chen, Li,Zhan, Zhuang-Ping

supporting information; experimental part, p. 3215 - 3222 (2011/02/23)

An efficient cascade methodology toward chemoselective synthesis of N-fused heterocycles including 9H-pyrrolo[1,2-a]indole, 3H-pyrrolo[1,2-a]indole and 1H-pyrrolo[1,2-a]indole derivatives has been developed. This transformation proceeds via a silver(I) triflate-catalyzed consecutive Friedel-Crafts reaction/N-C bond formation sequence between readily available propargyl alcohols and 3-substituted 1H-indoles. Not only is excellent chemoselectivity observed according to the substitution patterns of propargyl alcohols, but also the Lewis acid-catalyzed N-C bond formation process can be carried out under base- and ligand-free conditions.
