89992-76-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89992-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,9 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89992-76:
(7*8)+(6*9)+(5*9)+(4*9)+(3*2)+(2*7)+(1*6)=217
217 % 10 = 7
So 89992-76-7 is a valid CAS Registry Number.

Synthesis of β-D-mannosides from β-D-glucosides via an intramolecular SN2 reaction at C-2
Gunther,Kunz
, p. 217 - 241 (2007/10/02)
The selective synthesis of β-D-mannosides was achieved by first synthesizing β-D-glucosides that carry an N-phenylcarbamoyl protecting group at O-3. These derivatives were transformed into the corresponding β-D-mannosides by intramolecular nucleophilic su
