99823-65-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99823-65-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,2 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99823-65:
(7*9)+(6*9)+(5*8)+(4*2)+(3*3)+(2*6)+(1*5)=191
191 % 10 = 1
So 99823-65-1 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
