184920-21-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 184920-21-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,4,9,2 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 184920-21:
(8*1)+(7*8)+(6*4)+(5*9)+(4*2)+(3*0)+(2*2)+(1*1)=146
146 % 10 = 6
So 184920-21-6 is a valid CAS Registry Number.

Restricted Rotation Involving the Tetrahedral Carbon. LXIII. Endeavor toward Enhancing the Rotational Barrier in 9-s-Alkyltriptycenes

Oki, Michinori,Fukuda, Taizo,Asakura, Mitsuhiro,Toyota, Shinji

, p. 3267 - 3272 (2007/10/03)

In order to enhance barriers to rotation about the C9-substituent bond in 9-s-alkyltritpycenes, the secondary alkyl group was modified as well as the peri-substituent. The barrier was slightly enhanced by modifying the substituents but the extent was rather limited. This limitation was attributed to the limitation of the ways of preparation of 9-s-alkyltriptycenes that should give three stable retamers and carry substituents at peri-positions, where only 1,8-difluoro substituents could be used.
