Check Digit Verification of cas no
The CAS Registry Mumber 7098-22-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,9 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7098-22:
(6*7)+(5*0)+(4*9)+(3*8)+(2*2)+(1*2)=108
108 % 10 = 8
So 7098-22-8 is a valid CAS Registry Number.

A novel synthesis of branched high-molecular-weight (C40 +) long-chain alkanes

Many biological and geochemical questions remain concerning the structures, functions, and properties of naturally occurring high-molecular-weight (C 40+) alkanes with various mid-chain alkylation patterns. Above C40, these alkanes are exceedingly difficult to separate and purify, and syntheses can be blocked by the low solubility of intermediates. To overcome these problems, a facile three-step synthesis employing the alkylation of 1,3-dithiane with a suitable α,ω-dibromoalkane was developed. Bisalkylation of the bis(dithianyl)alkane intermediate with the appropriate 1-bromoalkane and subsequent desulfurization with Raney nickel furnished the desired long-chain alkane. Long-chain alkanes modified at mid-chain and/or symmetrically near the chain termini (or unmodified, i.e., long-chain n-paraffins) are accessible by the selection of appropriate bromoalkanes. Nine mid-chain methylated (C38H78 to C53H 108), one symmetrical terminal-chain dimethylated (C 40H82), and four linear (C44H90 to C58H118) long-chain alkanes were synthesized by using this approach. High-temperature gas chromatography (HTGC) was found to have important advantages for evaluating the purity of the synthetic high-molecular-weight alkanes.
