Check Digit Verification of cas no
The CAS Registry Mumber 26643-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,6,4 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 26643-91:
(7*2)+(6*6)+(5*6)+(4*4)+(3*3)+(2*9)+(1*1)=124
124 % 10 = 4
So 26643-91-4 is a valid CAS Registry Number.

Manganese-Catalyzed Dual-Deoxygenative Coupling of Primary Alcohols with 2-Arylethanols
Wang, Yujie,Shao, Zhihui,Zhang, Kun,Liu, Qiang

Reported herein is a general and efficient dual-deoxygenative coupling of primary alcohols with 2-arylethanols catalyzed by a well-defined Mn/PNP pincer complex. This reaction is the first example of the catalytic dual-deoxygenation of alcohols using a non-noble-metal catalyst. Both deoxygenative homocoupling of 2-arylethanols (17 examples) and their deoxygenative cross-coupling with other primary alcohols (20 examples) proceeded smoothly to form the corresponding alkenes by a dehydrogenation and deformylation reaction sequence.
