(8*1)+(7*2)+(6*8)+(5*3)+(4*1)+(3*6)+(2*1)+(1*3)=112
112 % 10 = 2
So 128316-13-2 is a valid CAS Registry Number.

CHEMISTRY OF OXALYL DERIVATIVES OF METHYL KETONES XLVII. REACTION OF N-ARYLAROYLPYRUVAMIDES WITH DIPHENYLDIAZOMETHANE

Brigadnova, E. V.,Maslivets, A. M.,Andreichikov, Yu. S.

, p. 274 - 277 (2007/10/02)

N-Aryl-4-aryl-3-diphenylmethyl-2,4-dioxobutyramides were obtained from N-arylaroylpyruvamides and diphenyldiazomethane.At 110 deg C in toluene they were converted into N-aryl-3-aryl-2-diphenylmethyl-3-oxopropionamides.By boiling in acetic acid they were converted into 1,5-diaryl-4-diphenylmethyl-2,3-dihydro-2,3-pyrrolediones.
