1173173-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1173173-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,1,7 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1173173-75:
(9*1)+(8*1)+(7*7)+(6*3)+(5*1)+(4*7)+(3*3)+(2*7)+(1*5)=145
145 % 10 = 5
So 1173173-75-5 is a valid CAS Registry Number.

experimental part, p. 3959 - 3962 (2009/10/11)
An InCl3-catalyzed one-pot synthesis of 2-pyrrolo-3′-yloxindoles was achieved via three-component reaction of 3-phenacylideneoxindole, β-keto ester, and ammonium acetate at reflux by a sequential Michael addition followed by Paal-Knorr condensa
