Check Digit Verification of cas no

The CAS Registry Mumber 142818-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,1 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142818-04:
(8*1)+(7*4)+(6*2)+(5*8)+(4*1)+(3*8)+(2*0)+(1*4)=120
120 % 10 = 0
So 142818-04-0 is a valid CAS Registry Number.

FACILE SYNTHETIC METHODS FOR 3- AND 5-TRIFLUOROMETHYL-4-TRIFLUOROACETYLPYRAZOLES AND THEIR CONVERSION INTO PYRAZOLE-4-CARBOXYLIC ACIDS

Okada, Etsuji,Masuda, Ryoichi,Hojo, Masaru

, p. 791 - 798 (2007/10/02)

3- and 5-Trifluoromethyl-4-trifluoroacetylpyrazoles (4 and 5) were easily synthesized in excellent yields by reaction of β,β-bis(trifluoroacetyl)vinyl ethers 1, sulfides 2, and -amines 3 with hydrazines.Hydrolysis of these compounds (4 and 5) with aqueous potassium hydroxide gave the corresponding pyrazole-4-carboxylic acids (6 and 7) in high yields.
