Check Digit Verification of cas no

The CAS Registry Mumber 108976-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,9,7 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 108976-72:
(8*1)+(7*0)+(6*8)+(5*9)+(4*7)+(3*6)+(2*7)+(1*2)=163
163 % 10 = 3
So 108976-72-3 is a valid CAS Registry Number.

Photochemical Reaction of Ethyl 3-Oxo-2,4-diphenylbutanoate

Yoshioka, Michikazu,Osawa, Haruhiko,Fukuzawa, Shinji

, p. 877 - 879 (1982)

Irradiation of ethyl 3-oxo-2,4-diphenylbutanoate in hexane gave the products formed by recombination of the radicals (Ph-CH2 and/or Ph-CH-CO2Et)resulting from decarbonylation, together with small amounts of 1,2-diphenylethanol and ethyl α-hydroxyphenylacetate, whereas in benzene no 1,2-diphenylethanol was found.Under oxygen an increased amount of ethyl α-hydroxyphenylacetate and no radical recombination products were observed.
