Check Digit Verification of cas no
The CAS Registry Mumber 4675-57-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,7 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4675-57:
(6*4)+(5*6)+(4*7)+(3*5)+(2*5)+(1*7)=114
114 % 10 = 4
So 4675-57-4 is a valid CAS Registry Number.

Synthesis of ω-Unsaturated Acids
Mirviss, Stanley B.
, p. 1948 - 1951 (2007/10/02)
A short, high-yield method for the synthesis of ω-unsaturated acids have been developed that precludes any double-bond migration or hydrogenation.Key is the coupling reaction between Grignards of ω-unsaturated alkyl halides and the bromomagnesium salt of ω-bromo fatty acids.The reaction has been successfully extended to ω-bromo nitriles.The use of ω-chloro acids or α-bromo acids gives lower yields of heterocoupling products and substantial homocoupling.A catalyst study shows Li2CuCl4 to yield the most heterocoupling of several catalysts tried for the chloro acids, and Ni(II) or Cu(I) are best for the α-bromo acids.
