Check Digit Verification of cas no

The CAS Registry Mumber 1140920-25-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,0,9,2 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1140920-25:
(9*1)+(8*1)+(7*4)+(6*0)+(5*9)+(4*2)+(3*0)+(2*2)+(1*5)=107
107 % 10 = 7
So 1140920-25-7 is a valid CAS Registry Number.

A facile synthesis of N,3-disubstituted indoles and 3-hydroxyl indolines via an intramolecular SNAr of fluorinated amino alcohols

Chen, Cheng-yi,Reamer, Robert A.

, p. 1529 - 1532 (2009)

In this Letter, we describe a practical and highly versatile method for the preparation of N,3-disubstituted indoles and 3-hydroxyl indolines. This synthetic strategy relies on an epoxide-opening followed by an intramolecular SNAr of the result
