173559-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173559-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,5,5 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 173559-89:
(8*1)+(7*7)+(6*3)+(5*5)+(4*5)+(3*9)+(2*8)+(1*9)=172
172 % 10 = 2
So 173559-89-2 is a valid CAS Registry Number.

Stereochemical basis for the insecticidal activity of carbamoylated and acylated pyrazolines
Hasan, Riaz
, p. 105 - 112 (2007/10/03)
Methyl 3-(4-chlorophenyl)-1-[N-(4-chlorophenyl)carbamoyl]-4-methyl2-pyrazoline-4- carboxylate was converted to corresponding (1R)- and (1S)-phenethyl esters via its carboxylic acid and acid chloride at the C-4 atom to separate the diastereomers. Their con
