Check Digit Verification of cas no
The CAS Registry Mumber 187159-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,1,5 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 187159-25:
(8*1)+(7*8)+(6*7)+(5*1)+(4*5)+(3*9)+(2*2)+(1*5)=167
167 % 10 = 7
So 187159-25-7 is a valid CAS Registry Number.

Synthesis and reactions of some ethyl 3-aroyl-4-aryl-2-pyrazoline-5-carboxylates
Faidallah,Makki,Elmassry,Hassan
, p. 101 - 105 (2007/10/03)
A series of ethyl 3-aroyl-4-aryl-2-pyrazoline-5-carboxylates 1 was prepared. Their reactions with bromine water, potassium permanganate and potassium hydroxide afforded the corresponding pyrazoles. With aryl and aroyl hydrazines the pyrazolines 1 gave the Schiff bases 9 while with hydrazine hydrate they yielded the corresponding acid hydrazides 11. Condensation of 11 with aromatic aldehydes gave the arylidene derivatives 12, which on cyclization with the proper reagent afforded 13 or 14. Reaction of 1 with hydrochloric acid gave the corresponding dipyrazolo-pyrazine derivatives 10.
