443761-69-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 443761-69-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,3,7,6 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 443761-69:
(8*4)+(7*4)+(6*3)+(5*7)+(4*6)+(3*1)+(2*6)+(1*9)=161
161 % 10 = 1
So 443761-69-1 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
