308366-28-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 308366-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,8,3,6 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 308366-28:
(8*3)+(7*0)+(6*8)+(5*3)+(4*6)+(3*6)+(2*2)+(1*8)=141
141 % 10 = 1
So 308366-28-1 is a valid CAS Registry Number.

Regulation of the flexibility of planar chiral [2.2]paracyclophane ligands and its significant impact on enantioselectivity in asymmetric reactions of diethylzinc with carbonyl compounds

Wu, Xun-Wei,Zhang, Tang-Zhi,Yuan, Ke,Hou, Xue-Long

, p. 2357 - 2365 (2007/10/03)

A series of planar chiral ligands derived from [2.2]paracyclophane were synthesized and applied as catalysts in enantioselective additions of diethylzinc to aldehydes and α,β-unsaturated ketones. When ligand 10 with a dimethyl hydroxymethyl as the substituent was used, the enantioselectivity of the reaction of diethylzinc with aldehydes was much higher than when using ligand 3c with diphenyl hydroxymethyl as the substituent. The situation was the same with the 1,4-addition of diethylzinc to α,β-unsaturated ketones with 63-83% ee being obtained when the hydroxymethyl substituted ligand 7b was used, while almost no enantioselectivity was afforded if ligand 3c was used. The role of planar chirality is also studied.
