214836-83-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 214836-83-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,8,3 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 214836-83:
(8*2)+(7*1)+(6*4)+(5*8)+(4*3)+(3*6)+(2*8)+(1*3)=136
136 % 10 = 6
So 214836-83-6 is a valid CAS Registry Number.

Towards the total synthesis of phorboxazoles A and B: Stereocontrolled synthesis of a C20-C32 subunit
Paterson, Ian,Arnott, Euan A.
, p. 7185 - 7188 (2007/10/03)
The C20-C32 phorboxazole subunit 4, containing 5 stereocentres, was prepared in 8 steps (34%) from ethyl ketone (S)-7. Key steps included a boron-mediated anti aldol reaction and an intramolecular hetero-michael reaction. Installatio
