Check Digit Verification of cas no

The CAS Registry Mumber 14160-11-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,1,6 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14160-11:
(7*1)+(6*4)+(5*1)+(4*6)+(3*0)+(2*1)+(1*1)=63
63 % 10 = 3
So 14160-11-3 is a valid CAS Registry Number.

Photochemical Cycloaddition of Thiocarbonyl Compounds to Diphenylketene and a Related Ketenimine

Coyle, John D.,Rapley, Patricia A.,Kamphuis, Johan,Bos, Hendrik J. T.

, p. 1957 - 1960 (2007/10/02)

Diphenylketene undergoes photocycloaddition with N-methylthiophthalimide, N-methyldithiophthalimide or xanthene-9-thione, to give a spiro-adduct containing a thietan-2-one ring.The photoproducts from the thioimide substrates are themselves photolabile, eliminating COS to form an alkene.Diphenyl-N-(p-tolyl)ketenimine gives analogous 2-iminothietanes on irradiation with the thioimides.
