175289-52-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 175289-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,2,8 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 175289-52:
(8*1)+(7*7)+(6*5)+(5*2)+(4*8)+(3*9)+(2*5)+(1*2)=168
168 % 10 = 8
So 175289-52-8 is a valid CAS Registry Number.

Selective reactions of the free hydroxyl groups of 2,3,4,3′,4′-penta-O-benzylsucrose
Jarosz, Slawomir
, p. 73 - 79 (2007/10/03)
Selective transformations of the free hydroxyl groups in 2,3,4,3′,4′-penta-O-benzylsucrose (1) were studied. Oxidation of 1 with the Swern reagent followed by reaction with Ph3P=CH-COOMe gave 2,3,4,3′,4′-penta-O-benzyl-1,6,6′-tris-(E)(C-carbome
