85995-43-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85995-43-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,9 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85995-43:
(7*8)+(6*5)+(5*9)+(4*9)+(3*5)+(2*4)+(1*3)=193
193 % 10 = 3
So 85995-43-3 is a valid CAS Registry Number.

Photocyclization of 2,6-Dichlorocinnamic Acid Derivatives to 5-Chlorocoumarin
Arad-Yellin, R.,Green, B. S.,Muszkat, K. A.
, p. 2578 - 2583 (2007/10/02)
On UV irradation, 2,6-dichlorocinnamic acid and its esters undergo photocyclization with elimination of the elements of HCl or RCl (R = alkyl or aryl) to yield 5-chlorocoumarin (2); amide derivatives yield the corresponding imino analogues.Low-temperature
