Check Digit Verification of cas no

The CAS Registry Mumber 1239752-32-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,7,5 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1239752-32:
(9*1)+(8*2)+(7*3)+(6*9)+(5*7)+(4*5)+(3*2)+(2*3)+(1*2)=169
169 % 10 = 9
So 1239752-32-9 is a valid CAS Registry Number.

Facile Synthesis and In Vitro Nitric Oxide Production Inhibitory Activity of Benzoxazoles

Park, Hyeong Jin,Kim, Jin-Kyung,Jun, Jong-Gab

, p. 743 - 749 (2018)

A Facile synthesis of natural benzoxazoles, nocarbenzoxazoles F (1), G (5) and their derivatives (2–4 and 6–8) was achieved from the commercially available inexpensive precursors with overall yields ranging from 15 to 49%. Our strategy to access this fami

2-substituted benzoxazole preparation method of compound

-

, (2016/10/20)

The invention relates to a preparing method of 2-substituted benzoxazole compounds. The compounds are obtained by reaction of products obtained by reaction of acyl chloride and o-nitrophenol or derivatives thereof under catalyzing of reducing agent ammonium formate, a solvent and palladium-containing agents. According to the method, the reaction condition is mild, environment is protected, raw materials are rich and easy to obtain, operation is easy, yield is high, and various kinds of performance are optimized.

Facile preparation of 2-substituted benzoxazoles and benzothiazoles via aerobic oxidation of phenolic and thiophenolic imines catalyzed by polymer-incarcerated platinum nanoclusters

Yoo, Woo-Jin,Yuan, Hao,Miyamura, Hiroyuki,Kobayashi, Shu

, p. 3085 - 3089 (2012/01/02)

Platinum nanoclusters supported on a polymer/carbon black composite material was found to be an excellent catalyst for the oxidative cyclization of phenolic and thiophenolic Schiff bases to 2-substituted benzoxazoles and benzothiazoles under ambient conditions. Copyright
