(7*5)+(6*6)+(5*1)+(4*3)+(3*5)+(2*0)+(1*7)=110
110 % 10 = 0
So 56135-07-0 is a valid CAS Registry Number.

Convenient stereoselective synthesis of β-perfluoroalkyl α,β-unsaturated esters via H?rner-Wadsworth-Emmons reactions

Yamazaki, Takashi,Mano, Noriko,Hikage, Reo,Kaneko, Tsutomu,Kawasaki-Takasuka, Tomoko,Yamada, Shigeyuki

, p. 8059 - 8066 (2015)

Condensation of H?rner-Wadsworth-Emmons reagents 3 and ketones 2 with a perfluoroalkyl (Rf) moiety prepared in situ was proved to be significantly efficient and powerful methods for the construction of a wide variety of α,β-unsaturated esters with Rf and R1 groups both at the β-position due to convenient avoidance of usually tedious as well as troublesome isolation steps of these ketones 2.
