82313-55-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82313-55-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,3,1 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82313-55:
(7*8)+(6*2)+(5*3)+(4*1)+(3*3)+(2*5)+(1*5)=111
111 % 10 = 1
So 82313-55-1 is a valid CAS Registry Number.

Triarylmethyl Systems, III. Synthesis of α-Arylparacyclophanes
Staab, Heinz A.,Ruland, Alfred,Kuo-chen, Chi
, p. 1755 - 1764 (2007/10/02)
As triarylmethyl systems with unusual sterical orientation of the aryl rings α-arylparacyclophanes with n = 5 - 8 (1a - d, 8a,b) were synthesized via the corresponding dithiaparacyclophanes (2a - d, 6a,b) and the disulfones (3a - d, 7a,b)
