220300-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220300-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,3,0 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 220300-25:
(8*2)+(7*2)+(6*0)+(5*3)+(4*0)+(3*0)+(2*2)+(1*5)=54
54 % 10 = 4
So 220300-25-4 is a valid CAS Registry Number.

A mild and efficient method for the synthesis of mixed adducts of 1,4-bis-benzyne
Winling, Alain,Russell, Richard A.
, p. 3921 - 3923 (2007/10/03)
Unsymmetrical adducts of 1,4-bis-benzyne ? have been prepared by the addition of dienes to mohobenzynes generated sequentially from 1,2,4,5-tetrakis(trimethylsilyl)benzene.
