Check Digit Verification of cas no

The CAS Registry Mumber 40377-66-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,7 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40377-66:
(7*4)+(6*0)+(5*3)+(4*7)+(3*7)+(2*6)+(1*6)=110
110 % 10 = 0
So 40377-66-0 is a valid CAS Registry Number.

Chemo-, Regio-, and stereoselective trifluoromethylation of styrenes via visible light-driven single-electron transfer (SET) and triplet-triplet energy transfer (TTET) processes

Lin, Qing-Yu,Xu, Xiu-Hua,Qing, Feng-Ling

, p. 10434 - 10446 (2015/02/19)

A process for tunable and chemo-, regio-, and stereoselective photocatalytic trifluoromethylation of styrenes was developed. Thermodynamically stable E-trifluoromethylated alkenes were prepared using Tognis reagent in the presence of Ru(bpy)3Cl2·6H2O under visible light irradiation, whereas less thermodynamically stable Z-trifluoromethylated alkenes were obtained by employing Umemotos reagent and photocatalyst Ir(ppy)3.
