40765-34-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40765-34-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,7,6 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40765-34:
(7*4)+(6*0)+(5*7)+(4*6)+(3*5)+(2*3)+(1*4)=112
112 % 10 = 2
So 40765-34-2 is a valid CAS Registry Number.

Photodegradation and photostability-indication of mequitazine
Abdel-Moety, Ezzat M.,Ibrahim, Mohamed A.,Rezk, Mamdouh R.
, (2009)
The photochemical behavior is investigated for mequitazine (MQ) illustrating possible mechanisms and photodegradation products formed. Accelerated photolysis is done for MQ under justified stress conditions by subjecting aqueous drug solutions to radiatio
