331463-81-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 331463-81-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,4,6 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 331463-81:
(8*3)+(7*3)+(6*1)+(5*4)+(4*6)+(3*3)+(2*8)+(1*1)=121
121 % 10 = 1
So 331463-81-1 is a valid CAS Registry Number.

Solid-supported acids for debenzylation of aryl benzyl ethers
Petchmanee, Thaninee,Ploypradith, Poonsakdi,Ruchirawat, Somsak
, p. 2892 - 2895 (2007/10/03)
Solid-supported acids have been investigated for aromatic debenzylation reactions. Stoichiometric amounts of solid-supported acids in refluxing toluene with or without 4 equiv of methanol effectively provided the desired aromatic debenzylation products of various systems in moderate to excellent yields (up to 98%).
