125416-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125416-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,4,1 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 125416-97:
(8*1)+(7*2)+(6*5)+(5*4)+(4*1)+(3*6)+(2*9)+(1*7)=119
119 % 10 = 9
So 125416-97-9 is a valid CAS Registry Number.

2-BENZOPYRYLIUM SALTS. 36. DISPROPORTIONATION OF 2-BENZOPYRYLIUM SALTS THROUGH PRIOR 4-1'DIMERIZATION
Verin, S. V.,Kuznetsov, E. V.,Zhadanov, Yu. A.
, p. 617 - 621 (2007/10/02)
It was observed that the disproportionation of 2-benzopyrylium salts proceeds through prior dimerization.Intermediates were isolated and identified.Assumptions regarding the mechanism of the transformation are expressed.
