126388-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126388-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,3,8 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 126388-92:
(8*1)+(7*2)+(6*6)+(5*3)+(4*8)+(3*8)+(2*9)+(1*2)=149
149 % 10 = 9
So 126388-92-9 is a valid CAS Registry Number.

REACTION OF 4-NITROPHTHALONITRILE WITH CARBONATE, NITRITE, AND FLUORIDE
Woehrle, Dieter,Knothe, Gerhard
, p. 3231 - 3240 (2007/10/02)
In DMSO and DMF at elevated temperatures, KF, KNO2, NaNO2, K2CO3, and Na2CO3 react with 4-nitrophthalonitrile to form 4,4'-oxybis(phthalonitrile) and, mostly, 4-hydroxyphthalonitrile.Formation ratios depend on reaction conditions.Intermediates are discussed.
