81520-71-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81520-71-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,2 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81520-71:
(7*8)+(6*1)+(5*5)+(4*2)+(3*0)+(2*7)+(1*1)=110
110 % 10 = 0
So 81520-71-0 is a valid CAS Registry Number.

Ring-opening glycosylation of a chitobiose oxazoline catalyzed by a non-chitinolytic mutant of chitinase
Sakamoto, Junji,Watanabe, Takeshi,Ariga, Yumiko,Kobayashi, Shiro
, p. 1180 - 1181 (2001)
Ring-opening glycosylation of a chitobiose oxazoline was exclusively achieved by catalysis of a mutated chitinase that is only active for the glycosylation and not for chitinolysis.
