Check Digit Verification of cas no
The CAS Registry Mumber 129218-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,1 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129218-89:
(8*1)+(7*2)+(6*9)+(5*2)+(4*1)+(3*8)+(2*8)+(1*9)=139
139 % 10 = 9
So 129218-89-9 is a valid CAS Registry Number.

A NOVEL PHOTOCHEMICAL 1,4-ACYL MIGRATION IN ENOL ESTERS. THE PHOTOLYSIS OF ENOL ACETATES OF 3-PHENYLPROPIOPHENONES
Alvaro, M.,Baldovi, V.,Garcia, H.,Miranda, M. A.,Primo, J.
, p. 3613 - 3614 (1987)
Photolysis of the enol acetates 1a, b gives the 1,4-diketones 4a, b by a mechanism involving a primary homolytic carbonyl-oxygen bond cleavage, followed by 1,2-hydrogen shift and in cage recombination.
