1020265-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1020265-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,2,6 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1020265-99:
(9*1)+(8*0)+(7*2)+(6*0)+(5*2)+(4*6)+(3*5)+(2*9)+(1*9)=99
99 % 10 = 9
So 1020265-99-9 is a valid CAS Registry Number.

Synthesis of C1- and C 3ν-symmetric porphyrin trimers based on triphenylmethane cores
Papamicael, Cyril A.,Mongin, Olivier,Gossauer, Albert
, p. 791 - 796 (2008/02/09)
This work describes the synthesis of a new class of tripodaphyrin derivatives with a triphenylmethane core. Both C 1- and C 3ν-symmetric tetrahedral large molecules with covalently linked rigid elements were obtained.
