65072-25-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65072-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,0,7 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 65072-25:
(7*6)+(6*5)+(5*0)+(4*7)+(3*2)+(2*2)+(1*5)=115
115 % 10 = 5
So 65072-25-5 is a valid CAS Registry Number.

Facile synthesis of new NLO-functionalized polyimides via Mitsunobu reaction
Yoon, Chong-Bok,Shim, Hong-Ku
, p. 2339 - 2344 (2007/10/03)
Three polyimides containing a nonlinear optical (NLO) chromophore were prepared through a new synthetic pathway. Coupling of dihydroxy and diimide compounds yielded the polyimide. Due to the mild conditions of polymerization, a chemically labile hemicyani
