142072-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142072-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,7 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142072-49:
(8*1)+(7*4)+(6*2)+(5*0)+(4*7)+(3*2)+(2*4)+(1*9)=99
99 % 10 = 9
So 142072-49-9 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
