403511-55-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 403511-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,5,1 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 403511-55:
(8*4)+(7*0)+(6*3)+(5*5)+(4*1)+(3*1)+(2*5)+(1*5)=97
97 % 10 = 7
So 403511-55-7 is a valid CAS Registry Number.

β-Galactosidase-catalyzed intramolecular transglycosylation
Komba, Shiro,Ito, Yukishige
, p. 8501 - 8505 (2001)
A novel transglycosylation strategy for efficient preparation of N-acetyllactosamine (Galβl→4GlcNAc, LacNAc) and sialyl LacNAc was developed using β-galactosidase from Bacillus circulans. In order to minimize the competing hydrolysis by forcing the enzyma
