222027-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 222027-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,0,2 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 222027-29:
(8*2)+(7*2)+(6*2)+(5*0)+(4*2)+(3*7)+(2*2)+(1*9)=84
84 % 10 = 4
So 222027-29-4 is a valid CAS Registry Number.

A synthetic approach to diaryl ethers using the Robinson annulation
Feng, Xianqi,Edstrom, Eric D.
, p. 99 - 105 (2007/10/03)
An alternative synthetic approach to diaryl ethers has been developed. In the key transformation, Robinson annulation of nonracemic aldehydes 16a,b, derived from L-glutamic acid 5-methyl ester and phenoxymethylvinyl ketone, provided α-phenoxyenones 17a,b.
