Check Digit Verification of cas no

The CAS Registry Mumber 75937-84-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,3 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75937-84:
(7*7)+(6*5)+(5*9)+(4*3)+(3*7)+(2*8)+(1*4)=177
177 % 10 = 7
So 75937-84-7 is a valid CAS Registry Number.

Synthesis of Renewable Lubricant Alkanes from Biomass-Derived Platform Chemicals

Gu, Mengyuan,Xia, Qineng,Liu, Xiaohui,Guo, Yong,Wang, Yanqin

, p. 4102 - 4108 (2017/10/31)

The catalytic synthesis of liquid alkanes from renewable biomass has received tremendous attention in recent years. However, bio-based platform chemicals have not to date been exploited for the synthesis of highly branched lubricant alkanes, which are currently produced by hydrocracking and hydroisomerization of long-chain n-paraffins. A selective catalytic synthetic route has been developed for the production of highly branched C23 alkanes as lubricant base oil components from biomass-derived furfural and acetone through a sequential four-step process, including aldol condensation of furfural with acetone to produce a C13 double adduct, selective hydrogenation of the adduct to a C13 ketone, followed by a second condensation of the C13 ketone with furfural to generate a C23 aldol adduct, and finally hydrodeoxygenation to give highly branched C23 alkanes in 50.6 % overall yield from furfural. This work opens a general strategy for the synthesis of high-quality lubricant alkanes from renewable biomass.
