92101-56-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 92101-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,0 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 92101-56:
(7*9)+(6*2)+(5*1)+(4*0)+(3*1)+(2*5)+(1*6)=99
99 % 10 = 9
So 92101-56-9 is a valid CAS Registry Number.

Takai-Utimoto reactions of oxoalkylhalides catalytic in chromium and cobalt

Wessjohann, Ludger A.,Schrekker, Henri S.

, p. 4323 - 4325 (2007)

The scope of chromium(II)/cobalt(I)-catalyzed Takai-Utimoto reactions was extended to substrates with unprotected reactive functional groups. In the presence of a higher chlorosilane and manganese the first chromium(II)/cobalt(I)-catalyzed version for the

Chromium-Catalyzed Linear-Selective Alkylation of Aldehydes with Alkenes

Hirao, Yuki,Kanai, Motomu,Katayama, Yuri,Mitsunuma, Harunobu

supporting information, (2020/11/18)

We developed a chromium-catalyzed, photochemical, and linear-selective alkylation of aldehydes with alkylzirconium species generated in situ from a wide range of alkenes and Schwartz's reagent. Photochemical homolysis of the C-Zr bond afforded alkyl radicals, which were then trapped by a chromium complex catalyst to generate the alkylchromium(III) species for polar addition to aldehydes. The reaction proceeded with high functional group tolerance at ambient temperature under visible-light irradiation.
