128980-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128980-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,8 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128980-28:
(8*1)+(7*2)+(6*8)+(5*9)+(4*8)+(3*0)+(2*2)+(1*8)=159
159 % 10 = 9
So 128980-28-9 is a valid CAS Registry Number.

Enzyme Catalysed Preparation of 6-O-Acylglucopyranosides
Adelhorst, Kim,Bjoerkling, Fredrik,Godtfredsen, Sven Erik,Kirk, Ole
, p. 112 - 115 (2007/10/02)
6-O-Monoesters of alkyl glucopyranosides have been prepared on a large scale in a more than 90percent yield by direct enzyme-catalysed esterification of glucopyranosides with long chain fatty acids in a solvent-free process.
