130743-10-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130743-10-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,4 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130743-10:
(8*1)+(7*3)+(6*0)+(5*7)+(4*4)+(3*3)+(2*1)+(1*0)=91
91 % 10 = 1
So 130743-10-1 is a valid CAS Registry Number.

, (2008/06/13)
The present invention relates to intermediates, pradimic acids and pradimic acid amides of the formula (II) STR1 wherein R is OH or NH2 ; R1 is hydrogen or a group of the formula STR2 with the proviso that when R is OH, R1 is not hydrogen; Y is OH or NR2 R3 ; R2 is hydrogen or methyl; R3 is hydrogen, C1-5 alkyl, or an amino protecting group; R4 is hydrogen, hydroxy protecting group, or β-D-xylosyl. The invention relates also to novel processes for the preparation of pradimic acids and pradimic acid amides, as well as novel pradimicin derivatives prepared therefrom.
