Check Digit Verification of cas no

The CAS Registry Mumber 28657-75-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,5 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 28657-75:
(7*2)+(6*8)+(5*6)+(4*5)+(3*7)+(2*7)+(1*5)=152
152 % 10 = 2
So 28657-75-2 is a valid CAS Registry Number.

Direct formation of secondary and tertiary alkylzinc bromides

Hanson, Mark V.

, p. 7205 - 7208 (1994)

The direct formation of secondary and tertiary alkylzinc bromides can be accomplished under mild conditions from the direct oxidative addition of Rieke zinc to secondary and tertiary alkyl bromides including remote functionalized halides.

MATTER OF COMPOSITION, SYNTHESIS, FORMULATION AND APPLICATION OF FL118 PLATFORM POSITIONS 7 AND 9-DERIVED ANALOGUES FOR TREATMENT OF HUMAN DISEASE

-

Paragraph 000118; 000120, (2020/04/25)

Described herein, are the chemical synthesis, matter of compositions, formulation, function, methods and uses of the FL118 platform Positions 7 and/or 9-derived analogues for treating cancer or other human diseases. Compounds derived from chemical modifications of the FL118 platform are employed alone or in combination with other anti-cancer agents to preclude, eliminate or reverse cancer phenotypes. This invention intends to realize unique personalized cancer treatment (personalized precision medicine) through application of a series of structural relevant individual FL118 platform-derived analogues, which target multiple cellular human disease-relevant proteins and their signaling pathways.

Palladium catalyzed decarboxylative acylation of arylboronic acid with ethyl cyanoacetate as a new acylating agent: Synthesis of alkyl aryl ketones

Yousuf, Md,Das, Tuluma,Adhikari, Susanta

, p. 8763 - 8770 (2015/11/10)

Palladium catalyzed acylation of arylboronic acid containing various functional groups was performed efficiently by ethyl cyanoacetate/substituted ethyl cyanoacetate as the acylating agent in aqueous triflic acid medium. The alkyl aryl ketones were obtained in good to excellent yields, first by addition of arylboronic acid to the nitrile group of ethyl cyanoacetate and their derivatives, followed by in situ decarboxylation of the resulting β-ketoester.
