119905-40-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119905-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119905-40:
(8*1)+(7*1)+(6*9)+(5*9)+(4*0)+(3*5)+(2*4)+(1*0)=137
137 % 10 = 7
So 119905-40-7 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.
