20923-70-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20923-70-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,2 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20923-70:
(7*2)+(6*0)+(5*9)+(4*2)+(3*3)+(2*7)+(1*0)=90
90 % 10 = 0
So 20923-70-0 is a valid CAS Registry Number.

A FREE RADICAL CHAIN MECHANISM FOR THE ISONITRILE - NITRILE REARRANGEMENT IN SOLUTION AND ITS INHIBITION.
Meier, Michael,Ruechardt, Christoph
, p. 4671 - 4674 (1983)
A large fraction of the isonitrile-nitrile rearrangement of t-alkyl isonitriles in solution follows a free radical chain mechanism of the addition-elimination type.
