50613-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50613-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,1 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 50613-98:
(7*5)+(6*0)+(5*6)+(4*1)+(3*3)+(2*9)+(1*8)=104
104 % 10 = 4
So 50613-98-4 is a valid CAS Registry Number.

Improved yields in the synthesis of spin-labeled fatty acids
Mravljak, Janez,Pecar, Slavko
, p. 3763 - 3771 (2007/10/03)
Paramagnetic amide side products (6a-g) have been isolated from the reaction mixture in the synthesis of spin-labeled fatty acids of the doxyl type. After their hydrolysis to the corresponding acid, 7, the overall yield of spin-labeled fatty acids is significantly increased compared with published procedures.
