Check Digit Verification of cas no

The CAS Registry Mumber 19027-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,2 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19027-81:
(7*1)+(6*9)+(5*0)+(4*2)+(3*7)+(2*8)+(1*1)=107
107 % 10 = 7
So 19027-81-7 is a valid CAS Registry Number.

Reductive Alkylation of α-Keto Imines Catalyzed by PTSA/FeCl3: Synthesis of Indoles and 2,3′-Biindoles

Naidu, P. Seetham,Kolita, Sinki,Sharma, Meenakshi,Bhuyan, Pulak J.

, p. 6381 - 6390 (2015/06/30)

A simple and efficient method for the synthesis of highly functionalized indoles and biindoles was developed. In the reaction protocol, three components were used in one pot and products were obtained in high yield in an easy workup procedure. The reactio

Synthesis and antifungal activity of 2-Ketophenyl-3 substituted aryl-1-thiazolidin-4-ones

Vats, Vishnu,Upadhyay,Sharma, Prathibha

, p. 1040 - 1044 (2011/12/05)

A new series of 2-ketophenyl-3-substituted aryl-1- thiazolidin-4- ones were synthesized by cyclocondensation of ketoazomethines and thioglycolic acid. Ketoazomethines were synthesized by condensation of phenyl glyoxal (prepared by partial oxidation of ace
