31840-26-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31840-26-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,8,4 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31840-26:
(7*3)+(6*1)+(5*8)+(4*4)+(3*0)+(2*2)+(1*6)=93
93 % 10 = 3
So 31840-26-3 is a valid CAS Registry Number.

Synthesis of 4-amino-6-chloro-1,3,5-triazin-2(1H)-ones

Bakharev,Gidaspov,Parfenov,Ulyankina,Zavodskaya,Selezneva,Suponitskii,Sheremetev

, p. 99 - 112 (2013/01/15)

Conditions for selective substitution for one chlorine atom in 2-(R,R-amino)-4,6-dichloro-1,3,5-triazines with a hydroxide ion were elaborated. Spectral and calculation methods showed that the products formed are in the lactam form, i.e., have the structure of 4-chloro-6-(R,R- amino)-1,3,5-triazin-2(1H)-ones.

Nucleophilic Aromatic Substitution in Heterocycles: Alcoholysis and Hydrolysis of 2-Anilino-4,6-dichloro-1,3,5-triazines

Renfrew, A. Hunter M.,Taylor, John A.,Whitmore, James M. J.,Williams, Andrew

, p. 2389 - 2394 (2007/10/02)

Kinetics are reported for the alkaline hydrolysis of 2-anilino-4,6-dichloro-1,3,5-triazines to yield the corresponding mono-hydroxy species.The pseudo-first-order rate constants are independent of general-base concentration and obey the rate law eqn. (i),
