(8*1)+(7*0)+(6*7)+(5*8)+(4*5)+(3*3)+(2*6)+(1*4)=135
135 % 10 = 5
So 107853-64-5 is a valid CAS Registry Number.

CHEMISTRY OF OXALYL DERIVATIVES OF METHYL KETONES. XLIII. SYNTHESIS OF 2-IMINO-2,3-DIHYDRO-3-FURANONES, THEIR HYDROLYSIS AND AMINOLYSIS

Andreichikov, Yu. S.,Shurov, S. N.,Zalesov, V. V.,Shapet'ko, N. N.

, p. 766 - 770 (2007/10/02)

N-substituted 2-imino-5-aryl-2,3-dihydro-3-furanones are produced during the thermal decarbonylation of 5-aryl-2,3-dihydro-2,3-furandiones in the presence of isocyanides.Primary and secondary amines open the ring in the products, leaidng to the formation of the amides of N-substituted 4-amino-4-aryl-2-oxo-3-butenoic acids.The acid hydrolysis of N-substituted 2-imino-5-aryl-2,3-dihydro-3-furanones leads to the corresponding amides of 4-aryl-2,4-dioxybutaric acids.
