84533-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84533-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,3 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 84533-91:
(7*8)+(6*4)+(5*5)+(4*3)+(3*3)+(2*9)+(1*1)=145
145 % 10 = 5
So 84533-91-5 is a valid CAS Registry Number.

Preparation of α-cyanobenzyl esters
-
, (2008/06/13)
New α-halobenzyl esters, intermediates for α-cyanobenzyl pyrethroid esters, are prepared by treating a benzaldehyde derivative with a pyrethroid acid halide. The resulting α-halobenzyl ester is treated with a water-soluble compound capable of generating cyanide ions (CN-) to give the corresponding α-cyanobenzyl esters.
