Bis-<α-methoxy-benzyl>-diselenid, also known as bis(α-methoxybenzyl) diselenide, is an organoselenium compound characterized by its molecular formula C16H18O2Se2. It is a colorless solid with a molecular weight of 399.23 g/mol. Bis-<α-methoxy-benzyl>-diselenid is formed by the linkage of two α-methoxybenzyl groups through a diselenide bridge, which consists of two selenium atoms bonded together. It is synthesized by reacting α-methoxybenzyl bromide with sodium selenide in the presence of a crown ether catalyst. Bis-<α-methoxy-benzyl>-diselenid is of interest in the field of organoselenium chemistry due to its potential applications in various chemical reactions and as a precursor to other organoselenium compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 6253-17-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,5 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6253-17:
(6*6)+(5*2)+(4*5)+(3*3)+(2*1)+(1*7)=84
84 % 10 = 4
So 6253-17-4 is a valid CAS Registry Number.
