19214-14-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19214-14-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,1 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19214-14:
(7*1)+(6*9)+(5*2)+(4*1)+(3*4)+(2*1)+(1*4)=93
93 % 10 = 3
So 19214-14-3 is a valid CAS Registry Number.

Intramolecular Photoaddition of Ketenes to Conjugated Cycloalkenones
Becker, Dan,Birnbaum, Dov
, p. 570 - 578 (2007/10/02)
Diazo ketones linked to cycloalkenones by a hydrocarbon chain were irradiated with UV light.The photochemically generated ketene is shown to add the enone forming 1,4-diketones in moderate yield.The scope and limitation of the cycloaddition for this proce
