Check Digit Verification of cas no

The CAS Registry Mumber 1418136-25-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,8,1,3 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1418136-25:
(9*1)+(8*4)+(7*1)+(6*8)+(5*1)+(4*3)+(3*6)+(2*2)+(1*5)=140
140 % 10 = 0
So 1418136-25-0 is a valid CAS Registry Number.

The facile synthesis of 2-bromoindoles via Cs2CO 3-promoted intramolecular cyclization of 2-(gem-dibromovinyl)anilines under transition-metal-free conditions

Li, Pinhua,Ji, Yong,Chen, Wei,Zhang, Xiuli,Wang, Lei

, p. 73 - 78 (2013/03/29)

2-Bromoindoles were readily prepared through a facile Cs2CO 3-promoted intramolecular cyclization of 2-(gem-bromovinyl)-N- methylsulfonylanilines in excellent yields under transition-metal-free conditions. This methodology could be extended to the synthesis of corresponding 2-chloroindoles. The reaction mechanism suggested that cyclization occurs through a key intermediate, phenylethynyl bromide, followed by cyclization in one-pot. The Royal Society of Chemistry.
