383422-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 383422-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,3,4,2 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 383422-23:
(8*3)+(7*8)+(6*3)+(5*4)+(4*2)+(3*2)+(2*2)+(1*3)=139
139 % 10 = 9
So 383422-23-9 is a valid CAS Registry Number.

The 2-(allyloxy) phenyl acetyl ester as a new relay protecting group for oligosaccharide synthesis
Arranz, Esther,Boons, Geert-Jan
, p. 6469 - 6471 (2007/10/03)
The 2-(allyloxy) phenyl acetyl group can be removed by a relay approach using Pd(PPh3)4 in combination with proton sponge, conditions that do not affect acetyl, benzoyl and levulinoyl esters. On the other hand, the acetyl and levulin
