220583-66-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220583-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,5,8 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 220583-66:
(8*2)+(7*2)+(6*0)+(5*5)+(4*8)+(3*3)+(2*6)+(1*6)=114
114 % 10 = 4
So 220583-66-4 is a valid CAS Registry Number.

Anti-aldol reactions of lactate-derived ketones. Application to the synthesis of (-)-tetrahydrolipstatin
Paterson,Doughty
, p. 393 - 394 (2007/10/03)
(-)-Tetrahydrolipstatin (1) was prepared with a high level of stereocontrol (>98% ds) by employing a boron-mediated, anti-selective, aldol coupling between the (R)-lactate-derived ketone 7 and the aldehyde 8.
