144422-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144422-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,2 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144422-89:
(8*1)+(7*4)+(6*4)+(5*4)+(4*2)+(3*2)+(2*8)+(1*9)=119
119 % 10 = 9
So 144422-89-9 is a valid CAS Registry Number.

Synthesis of alkene dipeptide isosteres employing the Wittig-Still rearrangement
Bol,Liskamp
, p. 6425 - 6438 (2007/10/02)
A new approach to the synthesis of alkene dipeptide isosteres is reported which features the use of the [2,3]-Wittig-Still rearrangement, carried out in hexanes. Employing this rearrangement alkene dipeptide isosteres of 'Gly-Xxx' are accessible starting
