127215-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127215-52-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,1 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127215-52:
(8*1)+(7*2)+(6*7)+(5*2)+(4*1)+(3*5)+(2*5)+(1*2)=105
105 % 10 = 5
So 127215-52-5 is a valid CAS Registry Number.

Asymmetric Diels-Alder Reactions of Chiral Isoprenyl Ethers with Reactive Dienophiles
Thiem, Roland,Rotscheidt, Klaus,Breitmaier, Eberhard
, p. 836 - 843 (2007/10/02)
The chiral alcohols 2 react with 3-ethoxy-2-methylacrolein (1) to yield chiral 3-alkoxy-2-methylacroleins 3, which are transformed to the chiral isoprenyl ethers 5 by Wittig methylenation in good yields. 1,3-Dienes 5 undergo cycloadditions with reac
