Check Digit Verification of cas no
The CAS Registry Mumber 44545-99-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,4,5,4 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 44545-99:
(7*4)+(6*4)+(5*5)+(4*4)+(3*5)+(2*9)+(1*9)=135
135 % 10 = 5
So 44545-99-5 is a valid CAS Registry Number.

THE MECHANISM OF THE NORRISH TYPE II REACTION OF α-KETO-ACIDS AND ESTERS
Davidson, R. Stephen,Goodwin, Dean,Violet, Ph. Fornier de
, p. 2485 - 2486 (2007/10/02)
Methyl-α-keto-octanoate undergoes a Type II reaction to give pent-1-ene and photophysical measurements show that this and the Type II reactions of α-keto-acids occur, contrary to previous claims, from the excited singlet state.
