252898-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 252898-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,8,9 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 252898-98:
(8*2)+(7*5)+(6*2)+(5*8)+(4*9)+(3*8)+(2*9)+(1*8)=189
189 % 10 = 9
So 252898-98-9 is a valid CAS Registry Number.

Application of a ring closing metathesis based linker to the solid phase synthesis of oligosaccharides
Knerr, Laurent,Schmidt, Richard R.
, p. 1802 - 1804 (1999)
A linker allowing a ring closing metathesis mediated cleavage of resin bound oligosaccharides in the form of their 1-O-allyl derivatives was designed. This new linker system for the solid phase synthesis of oligosaccharides via the trichloroacetimidate ap
