4645-16-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4645-16-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4645-16:
(6*4)+(5*6)+(4*4)+(3*5)+(2*1)+(1*6)=93
93 % 10 = 3
So 4645-16-3 is a valid CAS Registry Number.

Benzobutyrolactone derivatives, synthetic method and application thereof in preparation of bactericides

-

Paragraph 0041; 0042; 0043; 0044; 0045, (2018/04/03)

The invention discloses benzobutyrolactone derivatives, a synthetic method and application thereof in preparation of bactericides. The method comprises the following steps: taking sesquiterpene lactone pharmacophore alpha-methylene-gamma-butyrolactone as a lead compound, integrating benzofuranone pharmacophore, modifying at an alpha-methylene position, and performing directional derivative synthesis to obtain a series of alpha-alkenylene benzobutyrolactone compounds. The antibacterial activities of the compounds are determined, and two high-activity compounds with excellent industrialization development prospects are synthesized on the structure-effect basis. The compounds are used for controlling plant diseases caused by pathogenic bacteria such as wheat powdery mildew, wheat scab, take-all disease of wheat, wheat sharp eyespot, corn northern leaf blight, rice sheath blight disease, rice blast, cotton damping-off, phytoph-thora capsici leonian, botrytis cinerea, tomato leaf mould, tomato early/late blight, cucumber anthracnose, fusarium wilt of cucumber, sclerotinia rot of colza and the like.

Palladium-catalyzed hydrophenoxycarbonylation of internal alkynes by phenol and CO: The use of Zn for the formation of active catalyst

Kuniyasu, Hitoshi,Yoshizawa, Takahiro,Kambe, Nobuaki

scheme or table, p. 6818 - 6821 (2011/03/17)

The palladium-catalyzed hydrophenoxycarbonylation of internal alkynes by phenol and carbon monoxide was successfully realized by Pd(OAc)2/dppp catalyst system in the co-presence of Zn dust.

An ionic O → α- and β-vinyl carbamoyl translocation of 2-(O-carbamoyl) stilbenes

Reed, Mark A.,Chang, Michelle T.,Snieckus, Victor

, p. 2297 - 2300 (2007/10/03)

(Equation Presented) New anionic oxygen to α- and β-vinyl carbamoyl migration reactions, 17a and 26a-c → 18 and 30a-c, proceed under LDA-mediated conditions leading stereoselectively to highly substituted stilbenes bearing electron-donating and -withdrawing substituants. Compounds 17a and 26a-c are prepared by combination of efficient, directed ortho metalation, Sonogashira, and Suzuki-Miyaura cross-coupling procedures.
