126678-67-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 126678-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,6,7 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 126678-67:
(8*1)+(7*2)+(6*6)+(5*6)+(4*7)+(3*8)+(2*6)+(1*7)=159
159 % 10 = 9
So 126678-67-9 is a valid CAS Registry Number.

A robust nickel catalyst for cyanomethylation of aldehydes: Activation of acetonitrile under base-free conditions

Chakraborty, Sumit,Patel, Yogi J.,Krause, Jeanette A.,Guan, Hairong

supporting information, p. 7523 - 7526 (2013/07/26)

Nick of time: The nickel cyanomethyl complex 1 catalyzes the room temperature coupling of aldehydes with acetonitrile under base-free conditions. The catalytic system is long-lived and remarkably efficient with high turnover numbers (TONs) and turnover fr

One-pot nitrile aldolization/hydration operation giving β-hydroxy carboxamides

Goto, Akihiro,Naka, Hiroshi,Noyori, Ryoji,Saito, Susumu

supporting information; experimental part, p. 1740 - 1743 (2011/12/16)

Rhodium to the rescue: The formal aldol products of carboxamides (CONH 2) were obtained by using a RhI(OR) (R=H, Me) catalyst under essentially neutral pH and ambient conditions. This novel aldol strategy is based on the catalytic al

P(i-PrNCH2CH2)3N as a Lewis base catalyst for the synthesis of β-hydroxynitriles using TMSAN

Wadhwa, Kuldeep,Verkade, John G.

experimental part, p. 5683 - 5686 (2009/12/06)

(Equation Presented) Proazaphosphatrane 1a was found to be an efficient catalyst for synthesis of β-hydroxynitriles via the reaction of trimethylsilylacetonitrile (TMSAN) with aldehydes under mild reaction conditions and typically low catalyst loading (ca. 2 mol %). A variety of functional groups were tolerated, and good to excellent product yields were obtained.
