837-81-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 837-81-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 837-81:
(5*8)+(4*3)+(3*7)+(2*8)+(1*1)=90
90 % 10 = 0
So 837-81-0 is a valid CAS Registry Number.

Room-Temperature Guerbet Reaction with Unprecedented Catalytic Efficiency and Enantioselectivity

Lau, Kai Kiat,Liao, Gang,Ng, Teng Wei,Pan, Hui-Jie,Zhao, Yu

supporting information, p. 11384 - 11389 (2020/06/02)

We report herein an unprecedented highly efficient Guerbet-type reaction at room temperature (catalytic TON up to >6000). This β-alkylation of secondary methyl carbinols with primary alcohols has significant advantage of delivering higher-order secondary alcohols in an economical, redox-neutral fashion. In addition, the first enantioselective Guerbet reaction has also been achieved using a commercially available chiral ruthenium complex to deliver secondary alcohols with moderate yield and up to 92 % ee. In both reactions, the use of a traceless ketone promoter proved to be beneficial for the catalytic efficiency.
