119138-84-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119138-84-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,1,3 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 119138-84:
(8*1)+(7*1)+(6*9)+(5*1)+(4*3)+(3*8)+(2*8)+(1*4)=130
130 % 10 = 0
So 119138-84-0 is a valid CAS Registry Number.

ENANTIOSELECTIVE TOTAL SYNTHESIS OF (+)-NEGAMYCIN
Tanner, David,Somfai, Peter
, p. 2373 - 2376 (2007/10/02)
An efficient enantioselective total synthesis of the antibiotic (+)-negamycin is described, the absolute stereochemistry deriving from (R)-(+)-malic acid and subsequent use of the Sharpless asymmetric epoxidation reaction.
