160938-53-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 160938-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,9,3 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 160938-53:
(8*1)+(7*6)+(6*0)+(5*9)+(4*3)+(3*8)+(2*5)+(1*3)=144
144 % 10 = 4
So 160938-53-4 is a valid CAS Registry Number.

ELECTROCHEMICAL REDUCTION OF PRISTINAMYCIN IA AND RELATED STREPTOGRAMINS IN AQUEOUS ACIDIC MEDIUM

Largeron, M.,Vuilhorgne, M.,Potier, I. Le,Auzeil, N.,Bacque, E.,and al.

, p. 6307 - 6332 (2007/10/02)

The electrochemical reduction of the picolinoyl residue of pristinamycinIA and related streptogramins was performed at a mercury cathode, in aqueous medium.The presence of a peptidic lactone residue at the amide nitrogen atom markedly modified the expected cathodic behaviour of pyridyl carboxamides: in particular, we observed the reduction of the pyridyl ring into tetrahydropyridine derivatives.Thanks to a series of model heterocyclic carboxamides, increasing steric hindrance at the amide nitrogen position was shown to lead to enhanced reduction of the heterocyclic ring.
