128402-09-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128402-09-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,0 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128402-09:
(8*1)+(7*2)+(6*8)+(5*4)+(4*0)+(3*2)+(2*0)+(1*9)=105
105 % 10 = 5
So 128402-09-5 is a valid CAS Registry Number.

Photochemistry of Substituted 2-Benzoylcyclohexanones
Hasegawa, Tadashi,Yang, Yiming,Yoshioka, Michikazu
, p. 3488 - 3490 (2007/10/02)
The photoreactivities of substituted 2-benzoylcyclohexanones were distinguished as three different types; 1) the exclusive Norrish Type II cleavage when there were no alkyl groups on the 2-nor on the ortho position, 2) the benzoyl group shift from the 2-
