70093-19-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70093-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,0,9 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 70093-19:
(7*7)+(6*0)+(5*0)+(4*9)+(3*3)+(2*1)+(1*9)=105
105 % 10 = 5
So 70093-19-5 is a valid CAS Registry Number.

A Scalable Method for Regioselective 3-Acylation of 2-Substituted Indoles under Basic Conditions
Johansson, Henrik,Urruticoechea, Andoni,Larsen, Inna,Sejer Pedersen, Daniel
, p. 471 - 481 (2015/08/25)
Privileged structures such as 2-arylindoles are recurrent molecular scaffolds in bioactive molecules. We here present an operationally simple, high yielding and scalable method for regioselective 3-acylation of 2-substituted indoles under basic conditions
