108212-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108212-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,1 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 108212-58:
(8*1)+(7*0)+(6*8)+(5*2)+(4*1)+(3*2)+(2*5)+(1*8)=94
94 % 10 = 4
So 108212-58-4 is a valid CAS Registry Number.

Total Synthesis of 7,7-, 10,10-, and 13,13-Difluoroarachidonic Acids
Kwok, Pui-Yan,Muellner, Frank W.,Chen, Chien-Kuang,Fried, Josef
, p. 3684 - 3692 (1987)
General methodology is desribed for the synthesis of polyunsaturated fatty acids, in which one of the methylene groups between cis double bonds is replaced by a CF2 group.This is exemplified by the preparation of 7,7-, 10,10-, and 13,13-difluoroarachidoni
