Check Digit Verification of cas no

The CAS Registry Mumber 87019-98-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,1 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87019-98:
(7*8)+(6*7)+(5*0)+(4*1)+(3*9)+(2*9)+(1*8)=155
155 % 10 = 5
So 87019-98-5 is a valid CAS Registry Number.

Deaminative Olefination of Methyl N-Heteroarenes by an Amine Oxidase Inspired Catalyst

Thorve, Pradip Ramdas,Maji, Biplab

supporting information, p. 542 - 547 (2021/01/26)

We explored the bioinspired o-quinone cofactor catalyzed aerobic primary amine dehydrogenation for a cascade olefination reaction with nine different methyl N-heteroarenes, including pyrimidines, pyrazines, pyridines, quinolines, quinoxolines, benzimidazoles, benzoxazoles, benzthiazoles, and triazines. An o-quinone catalyst phd (1,10-phenanthroline-5,6-dione) combined with a Br?nsted acid catalyzed the reaction. N-Heteroaryl stilbenoids were synthesized in high yields and (E)-selectivities under mild conditions using oxygen (1 atm) as the sole oxidant without needing transition-metal salt, ligand, stoichiometric base, or oxidant.

Porous Crystalline Olefin-Linked Covalent Organic Frameworks

Lyu, Hao,Diercks, Christian S.,Zhu, Chenhui,Yaghi, Omar M.

supporting information, p. 6848 - 6852 (2019/05/10)

The first unsubstituted olefin-linked covalent organic framework, termed COF-701, was made by linking 2,4,6-trimethyl-1,3,5-triazine (TMT) and 4,4′-biphenyldicarbaldehyde (BPDA) through Aldol condensation. Formation of the unsubstituted olefin (-CHa?CH-)

Suzuki-Miyaura cross-coupling reactions of potassium alkenyltrifluoroborates

Molander, Gary A.,Bernardi, Carmem R.

, p. 8424 - 8429 (2007/10/03)

We have previously reported that the palladium-catalyzed cross-coupling reaction of air-stable potassium alkenyltrifluoroborates with aryl halides and triflates proceeds readily with good yields. Recent progress in outlining the scope and limitations of s
