Check Digit Verification of cas no

The CAS Registry Mumber 1499198-35-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,9,9,1,9 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1499198-35:
(9*1)+(8*4)+(7*9)+(6*9)+(5*1)+(4*9)+(3*8)+(2*3)+(1*5)=234
234 % 10 = 4
So 1499198-35-4 is a valid CAS Registry Number.

Benzylamine as Hydrogen Transfer Agent: Cobalt-Catalyzed Chemoselective C=C Bond Reduction of β-Trifluoromethylated α,β-Unsaturated Ketones via 1,5-Hydrogen Transfer

Li, Xuewei,Wu, Xiaoting,Tang, Liang,Xie, Fang,Zhang, Wanbin

, p. 3835 - 3839 (2019/11/11)

An efficient cobalt-catalyzed chemoselective reduction of β-CF3-α,β-unsaturated ketones using benzylamine as hydrogen transfer agent involving intramolecular 1,5-hydrogen transfer is reported. The reaction proceeded smoothly with a relatively w

Regioselective 1,4-trifluoromethylation of α,β-unsaturated ketones via a S-(trifluoromethyl)diphenylsulfonium salts/copper system

Okusu, Satoshi,Sugita, Yutaka,Tokunaga, Etsuko,Shibata, Norio

supporting information, p. 2189 - 2193 (2013/11/19)

Regioselective conjugate 1,4-trifluoromethylation of α,β- unsaturated ketones by the use of shelf-stable electrophilic trifluoromethylating reagents, S-(trifluoromethyl)diphenylsulfonium salts and copper under mild conditions is described. A wide range of acyclic aryl-aryl-enones and aryl-alkyl-enones were converted into β- trifluoromethylated ketones in low to moderate yields.
