54891-90-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54891-90-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,9 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 54891-90:
(7*5)+(6*4)+(5*8)+(4*9)+(3*1)+(2*9)+(1*0)=156
156 % 10 = 6
So 54891-90-6 is a valid CAS Registry Number.

Syntheses with 1,3-Dithietanes. XIII. Syntheses of Condensed Heterocycles from 5-Thioxo-3-pyrazoline-4-carboxylates

Peseke, K.,Vogel, C.,Blaesche, J.,Kollhof, K.-H.

, p. 639 - 651 (2007/10/02)

3-Amino-2-aroyl-5-thioxo-4-pyrazoline-4-carboxylates 1d-f react with bromoacetaldehydediethylacetale, phenacyl bromides, ethyl bromopyruvate, ethyl α-chloro-acetate or chloroacetylacetone to give ethyl dihydropyrazolothiazolecarboxylates 2, 4, 5 or 7.The derivatives of ethyl tetrahydropyrazolothiazolecarboxylates 8 or 9 are obtained by reaction of 1d-f with ethyl β-anilino-α-chloro-crotonate and oxalylchloride, respectively.The ethyl methylthiopyrazolinecarboxylate 10 d and an excess of hydrazine hydrate afford pyrazolopyrazole 11.Compounds 10 react with phenyl isocyanate to give pyrazolooxazin-6-ones 13.The dithietanes 12 and cinnamohydrazide yield pyrazolopyrazolecarboxylates 15.
