Check Digit Verification of cas no

The CAS Registry Mumber 105020-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,0,2 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105020-45:
(8*1)+(7*0)+(6*5)+(5*0)+(4*2)+(3*0)+(2*4)+(1*5)=59
59 % 10 = 9
So 105020-45-9 is a valid CAS Registry Number.

Synthesis and Transformations of Methyl (E)-2-(Acetylamino)-3-cyanoprop-2-enoate und Methyl (E)-2-(Benzoylamino)-3-cyanoprop-2-enoate, Versatile Reagents for the Preparation of Polyfunctional Heterocyclic Systems

Pizzioli, Lucija,Ornik, Brina,Svete, Jurij,Stanovnik, Branko

, p. 231 - 235 (2007/10/03)

Methyl (E)-2-(acetylamino)-3-cyanoprop-2-enoate (2a) and its 2-benzoyl analog 2b were prepared from the corresponding methyl (Z)-2-(acylamino)-3-(dimethylamino)propenoates 1. Multifunctional compounds 2 are versatile synthons for preparation of polysubstituted heterocyclic systems such as pyrroles 4, pyrimidines 5 and 6, pyridazines 7, pyrazoles 8, 9, and 11, and isoxazoles 10.

THE ASTOUNDING REACTION OF DIAZOMETHANE WITH DIMETHYL 2,3-DICYANOFUMARATE

Huisgen, Rolf,Mitra, Abhijit,Moran, Joaquin Rodriguez

, p. 2429 - 2436 (2007/10/02)

The title reaction afforded the pyrazole derivatives 3 and 4 as well as the N-methyl-1,2,3-triazolecarboxylic esters 5 - 7.The poly-step sequence was clarified; the key intermediates are the 1-pyrazoline 18, the 2-pyrazoline 2, the 4H-pyrazole 12, the pyrazole 22, and methyl cyanoformate.
