Check Digit Verification of cas no

The CAS Registry Mumber 66989-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,8 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66989-22:
(7*6)+(6*6)+(5*9)+(4*8)+(3*9)+(2*2)+(1*2)=188
188 % 10 = 8
So 66989-22-8 is a valid CAS Registry Number.

Antifungal Application of Rosin Derivatives from Renewable Pine Resin in Crop Protection

Gao, Yanqing,Hao, Jin,He, Xiaohua,Li, Jian,Shang, Shibin,Song, Jie,Song, Zhanqian,Tao, Pan,Wu, Chengyu

In the current work, we synthesized two series of dehydroabietyl amide derivatives from natural product rosin and evaluated their antifungal effects on Valsa mali, Phytophthora capsici, Botrytis cinerea, Sclerotinia sclerotiorum, and Fusarium oxysporum. In vitro and in vivo antifungal activities results indicated that rosin-based amide compounds containing thiophene heterocycles had better inhibitory effects on B. cinerea. In particular, compound 5b (5-fluoro-2-thiophene dehydroabietyl amide) exhibited the excellent antifungal properties against B. cinerea with an EC50 of 0.490 mg/L, which was lower compared to the positive control penthiopyrad (0.562 mg/L). Physiological and biochemical studies showed that the primary action mechanism of compound 5b on B. cinerea changes mycelial morphology, increases cell membrane permeability, and inhibits the TCA pathway in respiratory metabolism. Furthermore, QSAR and SAR studies revealed that charge distribution of rosin-based amides derivatives have a key role in the antifungal activity through the hydrogen bonding, conjugation, and electrostatic interaction between the compounds and the receptors of the target. To sum up, this study contributes to the development of rosin-based antifungal agents with a novel structure and preferable biological activity.

1-(1)-dehydroabietylimidazolium salts as enantiomer discriminators for NMR spectroscopy

Gunaratne, H.Q. Nimal,Laaksonen, Tiina,Seddon, Kenneth R.,W?h?l?, Kristiina

, p. 845 - 856 (2017/07/07)

Nine new (+)-dehydroabietylimidazolium salts were synthesised and studied as chiral solvating agents for several different racemic aromatic and non-aromatic carboxylate salts. These cationic chiral solvating agents resolve racemic ionic analytes better than non-ionic ones. Bis(dehydroabietylimidazolium) bis(trifluoromethanesulfonimide) gave the best discrimination for the enantiomers of carboxylate salts. Its resolution behaviour was studied by an NMR titration experiment, which indicated 1 : 1 complexation with the racemic analyte. The dehydroabietylimidazolium salts were also useful in enantiomeric excess (ee) determinations, and for the recognition of chirality of racemic aromatic and nonaromatic a-substituted carboxylic acids.
