29639-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 29639-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,6,3 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 29639-21:
(7*2)+(6*9)+(5*6)+(4*3)+(3*9)+(2*2)+(1*1)=142
142 % 10 = 2
So 29639-21-2 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.
