103259-25-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103259-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,5 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103259-25:
(8*1)+(7*0)+(6*3)+(5*2)+(4*5)+(3*9)+(2*2)+(1*5)=92
92 % 10 = 2
So 103259-25-2 is a valid CAS Registry Number.

, p. 3308 - 3314 (2007/10/02)
A simple synthesis of 1,8,13- and 1,8,16-trisubstituted triptycenes is described.Diels-Alder reaction of 1,8-disubstituted anthracenes with ortho-substituted benzynes gave 15 new triptycene compounds as mixtures of the syn (1,8,13) and anti (1,8,16) trisu
