1419786-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1419786-57-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,9,7,8 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1419786-57:
(9*1)+(8*4)+(7*1)+(6*9)+(5*7)+(4*8)+(3*6)+(2*5)+(1*7)=204
204 % 10 = 4
So 1419786-57-4 is a valid CAS Registry Number.

Synthesis of New 1,3,4-Thiadiazole Derivatives Containing of Morpholine Ring
Hamidian,Afrooz,Fozooni
, p. 487 - 489 (2013/02/22)
The synthesis of new of 1,3,4-thiadiazole derivatives containing of morpholine ring are investigated. In this study, the derivatives of naphthol, amine and phenol are reacted with 4-morpholine carbonyl chloride. Then, prepared solutions are added to diazo
