89091-67-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89091-67-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,9 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89091-67:
(7*8)+(6*9)+(5*0)+(4*9)+(3*1)+(2*6)+(1*7)=168
168 % 10 = 8
So 89091-67-8 is a valid CAS Registry Number.

ENOLATE CLAISEN REARRANGEMENT OF GLYCOLATE ESTERS
Kallmerten, James,Gould, Thomas J.
, p. 5177 - 5180 (2007/10/02)
The enolate Claisen rearrangement of O-protected allylic glycolates yields functionalized acyclic systems with high syn and anti stereoselectivity.This procedure is the key step in a short synthesis of threo-4-methylheptan-3-ol, an aggregation pheromone o
