Check Digit Verification of cas no
The CAS Registry Mumber 115315-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,3,1 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 115315-95:
(8*1)+(7*1)+(6*5)+(5*3)+(4*1)+(3*5)+(2*9)+(1*5)=102
102 % 10 = 2
So 115315-95-2 is a valid CAS Registry Number.

Haloacetylated enol ethers. 11 [16]. Synthesis of 1-methyl- and 1- phenyl pyrazole-3(5)-ethyl esters. A one-pot procedure

A one-pot synthesis of 1-methyl- and 1-phenylpyrazole-3(5)-ethyl esters 2,3a-e by the cyclocondensation of β-alkoxyvinyl trichloromethyl ketones 1a- e with methyl and phenyl hydrazine hydrochloride under mild conditions, is reported. A study using compounds la-e with different substituents proved that these are versatile building blocks for the synthesis of pyrazole derivatives, having a 3(5)-ethoxycarbonyl substituent in good yields (60- 89%). The hydrazine and β-alkoxyvinyl trichloromethyl ketone substituent effects on the reaction regiochemistry on the formation of the 1,3- and 1,5- isomer were observed.
