205180-53-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205180-53-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,1,8 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 205180-53:
(8*2)+(7*0)+(6*5)+(5*1)+(4*8)+(3*0)+(2*5)+(1*3)=96
96 % 10 = 6
So 205180-53-6 is a valid CAS Registry Number.

Structures of charge-perturbed or sterically overcrowded molecules, 108 [1] structural changes of tetraphenyl-p-quinodimethane on twofold reduction to its dianion
Bock, Hans,Arad, Claudia,Naether, Christian,Goebel, Ilka,John, Andreas
, p. 1391 - 1399 (2007/10/03)
The two-electron reduction of tetraphenyl-p-quinodimethane M via its radical anion M to its dianion M is explored both by cyclovoltammetry and ESR/ENDOR spectroscopy. Contact of the diglyme solution with added 15-crown-5 under aprotic condition
