134235-70-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134235-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,3 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134235-70:
(8*1)+(7*3)+(6*4)+(5*2)+(4*3)+(3*5)+(2*7)+(1*0)=104
104 % 10 = 4
So 134235-70-4 is a valid CAS Registry Number.

Synthesis of the methyl 3-amino-3-deoxy-α- and β-D-allopyranosides and -allofuranosides
Baer, Hans H.,Gan, Yuchen
, p. 233 - 245 (2007/10/02)
Methyl 3-amino-3-deoxy-α-D-allopyranoside was synthesized from methyl 2-O-benzoyl-4,6-O-benzylidene-α-D-glucopyranoside in a 5-step sequence involving trifluoromethylsulfonylation, azide displacement, deprotection, and catalytic hydrogenation.On displacem
