52121-66-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52121-66-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,2 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 52121-66:
(7*5)+(6*2)+(5*1)+(4*2)+(3*1)+(2*6)+(1*6)=81
81 % 10 = 1
So 52121-66-1 is a valid CAS Registry Number.

Nickel-catalyzed guerbet type reaction: C-alkylation of secondary alcohols via double (de)hydrogenation

Babu, Reshma,Subaramanian, Murugan,Midya, Siba P.,Balaraman, Ekambaram

supporting information, p. 3320 - 3325 (2021/05/31)

Acceptorless double dehydrogenative cross-coupling of secondary and primary alcohols under nickel catalysis is reported. This Guerbet type reaction provides an atom- and a step-economical method for the C-alkylation of secondary alcohols under mild, benign conditions. A broad range of substrates including aromatic, cyclic, acyclic, and aliphatic alcohols was well tolerated. Interestingly, the C-alkylation of cholesterol derivatives and the double C-alkylation of cyclopentanol with various alcohols were also demonstrated.
