122821-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122821-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,8,2 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122821-99:
(8*1)+(7*2)+(6*2)+(5*8)+(4*2)+(3*1)+(2*9)+(1*9)=112
112 % 10 = 2
So 122821-99-2 is a valid CAS Registry Number.

Synthesis of the Brevetoxin B IJK Ring System
Nicolaou, K. C.,Hwang, C.-K.,Duggan, M. E.
, p. 6682 - 6690 (2007/10/02)
A stereoselective synthesis of a functionalized system representing the IJK ring framework of brevetoxin B is reported.The synthesis begins with D-mannose pentaacetate and proceeds through intermediates 24 and 38, which serve as key cyclization precursors
