82737-57-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82737-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,3 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82737-57:
(7*8)+(6*2)+(5*7)+(4*3)+(3*7)+(2*5)+(1*7)=153
153 % 10 = 3
So 82737-57-3 is a valid CAS Registry Number.

SYNTHESIS AND REARRANGEMENT OF 5-ISOTHIOCYANATOPYRAZOLINES

Gotor, Vicente,Brieva, Rosario,Foces-Foces, Concepcion,Cano, Felix Hernandez

, p. 1783 - 1792 (2007/10/02)

1-(3-Iminoprop-1-enyl)-5-isothiocyanato-2-pyrazolines have been synthesized by reaction of hydrazine derivatives with carbon disulfide.These pyrazoline derivatives are precursors of pyrimidinylpyrazoles.

Reaction of Azines with Nitriles

Barluenga, Jose,Muniz, Laudina,Gotor, Vicente

, p. 454 - 455 (2007/10/02)

A new method for the synthesis of the hydrazine derivatives (3) by reaction of azines with nitriles is described; the hydrolysis of (3) yields the 3H-pyrazolopyrimidines (4).
