4887-74-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4887-74-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,8 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4887-74:
(6*4)+(5*8)+(4*8)+(3*7)+(2*7)+(1*4)=135
135 % 10 = 5
So 4887-74-5 is a valid CAS Registry Number.

N,N′-Diphenyldithiomalonodiamide: Structural Features, Acidic Properties, and In Silico Estimation of Biological Activity

Aksenov, N. A.,Aksenova, I. V.,Bespalov, A. V.,Dotsenko, V. V.,Pashchevskaya, N. V.,Sinotsko, A. E.

, p. 2136 - 2150 (2021/12/23)

Abstract: The spectral characteristics of dithiomalondianilide (N,N′-diphenyldithiomalonodiamide) were studied, and the dissociation constant was determined by potentiometric titration. Quantum-chemical methods at the B3LYP-D3BJ/6-311+G (2d,p) level were

STUDY OF DIRECTION OF CYCLIZATION OF MALONODITHIOAMIDES AS A METHOD OF INVESTIGATION OF REACTIVITY OF α-DIAZOTHIOACETAMIDES

Dankova, E. F.,Bakulev, V. A.,Morzherin, Yu. Yu.

, p. 931 - 936 (2007/10/02)

The reaction of malonothioamides with benzene-sulfonyl azide and 2-azido-3-ethylbenzthiazolium tatrafluoroborate gave amides of 2-diazothiomalonic acid, which underwent cyclization to a mixture of 5-N-R-amino-1,2,3-thiadiazole-4-carbothioamides and 5-amin

Spectrophotometric Determination of Cobalt and Nickel with N,N'-Diphenyldithiomalonamide and Elucidation of Structures of the Compounds

Pal, Tarasankar,Ganguly, Ashes,Pal, Anjali
