61679-84-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61679-84-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,6,7 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 61679-84:
(7*6)+(6*1)+(5*6)+(4*7)+(3*9)+(2*8)+(1*4)=153
153 % 10 = 3
So 61679-84-3 is a valid CAS Registry Number.

An improved procedure of Miyashita protocol for the preparation of ureidomethylene derivatives of 1,3-dicarbonyl compounds
Majee,Kundu,Santra,Hajra
, p. 124 - 126 (2014/02/14)
A facile method has been developed for the synthesis of ureidomethylene derivatives by the condensation of 1,3-dicarbonyl compounds, urea and trimethylorthoformate in presence of Zn(OTf)2 under solvent-free conditions. A variety of 1,3-dicarbon
