1176193-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1176193-81-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,6,1,9 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1176193-81:
(9*1)+(8*1)+(7*7)+(6*6)+(5*1)+(4*9)+(3*3)+(2*8)+(1*1)=169
169 % 10 = 9
So 1176193-81-9 is a valid CAS Registry Number.

Highly Efficient One-Pot Synthesis of Novel Propargylamine-Based Sulfonamides by an A3-Coupling Reaction
Abdoli, Morteza,Saeidian, Hamid,Kakanejadifard, Ali
, p. 2473 - 2476 (2016)
Novel propargylamine-based sulfonamides were synthesized in excellent yields by the copper(I) iodide catalyzed three-component coupling of propargylsulfonamides, morpholine, and aldehydes.
