649755-76-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 649755-76-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,7,5 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 649755-76:
(8*6)+(7*4)+(6*9)+(5*7)+(4*5)+(3*5)+(2*7)+(1*6)=220
220 % 10 = 0
So 649755-76-0 is a valid CAS Registry Number.

A practical building block for the synthesis of discodermolide
Loiseleur, Olivier,Koch, Guido,Wagner, Trixie
, p. 597 - 602 (2013/09/02)
A new highly diastereoselective and practical route to the lactone 6a which is used as a key building block for the total synthesis of the microtubule-stabilizing anticancer agent discodermolide is reported. This exploits the chiral auxiliary (4R)-4-isopr
