Check Digit Verification of cas no

The CAS Registry Mumber 20173-89-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,7 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20173-89:
(7*2)+(6*0)+(5*1)+(4*7)+(3*3)+(2*8)+(1*9)=81
81 % 10 = 1
So 20173-89-1 is a valid CAS Registry Number.

Oxygen-insensitive enzymatic reduction of oximes to imines

Heberling, Sabine,Girreser, Ulrich,Wolf, Stephanie,Clement, Bernd

, p. 354 - 365 (2006)

The reduction of oximes to imines under anaerobic and aerobic conditions was studied using (E)- and (Z)-2,4,6-trimethylacetophenone oxime, benzaldoxime and (E)-2,4,6-trimethylbenzaldoxime. Pig and human liver microsomes, pig liver mitochondria and cytosol

Study of the reactivity of organonickel sigma-complexes towards nitriles

Gafurov,Sakhapov,Babaev,Dobrynin,Kurmaz,Metlushka,Rizvanov, I. Kh.,Shaikhutdinova,Sinyashin,Yakhvarov

, p. 254 - 259 (2017/07/11)

The reactivity of organonickel sigma-complexes of type [NiBr(Ar)(bpy)], where Ar = 2,6-dimethylphenyl (Xyl), 2,4,6-trimethylphenyl (Mes), 2,4,6-triisopropylphenyl (Tipp), 2,4,6-tricyclohexylphenyl (Tchp), bpy = 2,2′-bipyridine, towards nitriles (acetonitr

Synthesis of Aryl Ketones by the Pd-Catalyzed C-H Activation of Arenes and Intermolecular Carbopalladation of Nitriles

Zhou, Chengxiang,Larock, Richard C.

, p. 2302 - 2303 (2007/10/03)

The palladium-catalyzed reaction of simple arenes and nitriles provides good to excellent yields of aryl ketones or the corresponding hindered imines. The addition of a small amount of DMSO increases the yields dramatically. Both intermolecular and intramolecular examples of this process are successful. This novel chemistry is believed to involve palladium-catalyzed C?H activation, followed by carbopalladation of the nitrile. Copyright
