Check Digit Verification of cas no

The CAS Registry Mumber 1351557-07-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,1,5,5 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1351557-07:
(9*1)+(8*3)+(7*5)+(6*1)+(5*5)+(4*5)+(3*7)+(2*0)+(1*7)=147
147 % 10 = 7
So 1351557-07-7 is a valid CAS Registry Number.

One-pot access to indolo[2,3- b]quinolines by electrophile-triggered cross-amination/friedel-crafts alkylation of indoles with 1-(2-tosylaminophenyl) ketones

Ali, Shaukat,Li, Ying-Xiu,Anwar, Saeed,Yang, Fang,Chen, Zi-Sheng,Liang, Yong-Min

experimental part, p. 424 - 431 (2012/02/13)

Activation of C2 and C3 of indoles by molecular iodine (I2) and base followed by in situ reaction with 1-(2-tosylaminophenyl)ketones or 2-tosylaminobenzaldehyde can afford highly substituted indolo(2,3-b)quinolines in moderate to excellent yields (up to 99%). The reaction provides a metal-free selective difunctionalization of indoles. The synthetic potential of the protocol has been illustrated by the synthesis of neocryptolepine and its 11-methyl analogue.
