119814-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119814-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,1 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 119814-58:
(8*1)+(7*1)+(6*9)+(5*8)+(4*1)+(3*4)+(2*5)+(1*8)=143
143 % 10 = 3
So 119814-58-3 is a valid CAS Registry Number.

STEREOCONTROLLED SYNTHESIS OF A C14-C20 BUILDING BLOCK FOR AMPHOTERICIN B USING A NOVEL WITTIG REARRANGEMENT
Bruecker, Reinhard
, p. 5747 - 5750 (2007/10/02)
The C14-C20 unit 11 of the polyene macrolide antibiotic amphotericin B (1) was synthesized from L-arabinose in 13 steps.The key step 7 -> 10 features diastereocontrol through asymmetric induction in a novel Wittig rearrangement.
