455901-41-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 455901-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,5,9,0 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 455901-41:
(8*4)+(7*5)+(6*5)+(5*9)+(4*0)+(3*1)+(2*4)+(1*1)=154
154 % 10 = 4
So 455901-41-4 is a valid CAS Registry Number.

A Cycloaddition Cascade Approach to the Total Synthesis of (-)-FR182877
Evans, David A.,Starr, Jeremy T.
, p. 13531 - 13540 (2007/10/03)
An asymmetric synthesis of the cytotoxic natural product, (-)-FR182877 (1), has been achieved. Chirality for the entire structure was established using two (4R)-4-benzyl-2-oxazolidinone-mediated boron aldol reactions. A 19-membered macrocarbocycle was syn
