214218-32-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 214218-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,2,1 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 214218-32:
(8*2)+(7*1)+(6*4)+(5*2)+(4*1)+(3*8)+(2*3)+(1*2)=93
93 % 10 = 3
So 214218-32-3 is a valid CAS Registry Number.

A synthesis of (+)-prelog-djerassi lactonic acid
Hiscock, Steven D.,Hitchcock, Peter B.,Parsons, Philip J.
, p. 11567 - 11580 (2007/10/03)
A new approach to the synthesis of Prelog-Djerassi Lactonic acid (1) is reported. A key step in this synthesis involves an Ireland-Claisen rearrangement/silicon-mediated fragmentation sequence to provide the carbon framework in (1).
